Expand the parameter parsing for block2mtd. It now accepts:
Ki, Mi, Gi - the official prefixes for binary multiples,
see http://physics.nist.gov/cuu/Units/binary.html,
ki - mistake on my side and analog to "k" for decimal multiples,
KiB, MiB, GiB - for people that prefer to add a "B" for byte,
kiB - combination of the above.
There were complaints about not accepting "k" for 1024. This has long
been common practice, but is known to lead to confusion. Hence the new
SI units and hence block2mtd only accepts units that cannot be confused
with decimal units. Diverging from common practice doesn't always please
people, even if the change is for the better.

Signed-off-by: Dave Jones <davej@redhat.com>
The previous patch had bugs (locking and refcount).
This one could also be related to the latest DELL reports.
But they only slip into this if a user prog (e.g. powersave daemon does when
AC got (un) plugged due to a scheme change) echos something to
/sys/../cpufreq/scaling_governor
while the frequencies got limited by BIOS.
This one works:
Subject: Max freq stucks at low freq if reduced by _PPC and sysfs gov access
The problem is reproducable by(if machine is limiting freqs via BIOS):
- Unplugging AC -> max freq gets limited
- echo ${governor} >/sys/.../cpufreq/scaling_governor (policy->user_data.max
gets overridden with policy->max and will never come up again.)
This patch exchanged the cpufreq_set_policy call to __cpufreq_set_policy and
duplicated it's functionality but did not override user_data.max.
The same happens with overridding min/max values. If freqs are limited and
you override the min freq value, the max freq global value will also get
stuck to the limited freq, even if BIOS allows all freqs again.
Last scenario does only happen if BIOS does not reduce the frequency
to the lowest value (should never happen, just for correctness...)

[PATCH] i2c-parport: Make type parameter mandatory
This patch forces the user to specify what type of adapter is present when
loading i2c-parport or i2c-parport-light. If none is specified, the driver
init simply fails - instead of assuming adapter type 0.
This alleviates the sometimes lengthy boot time delays which can be caused
by accidentally building one of these into a kernel along with several i2c
slave drivers that have lengthy probe routines (e.g. hwmon drivers).
Kconfig and documentation updated accordingly.

[PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/
dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64.
Currently all three arches compile it from arch/i386, which means that ia64
and x86_64 depend on things in arch/i386 that they wouldn't otherwise care
about.
This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing
trailing whitespace) and the associated Makefile changes. All three
architectures already set CONFIG_DMI in their top-level Kconfig files.

The current dc395x driver uses PIO to transfer up to 4 bytes which do not
get transferred by DMA (under unclear circumstances). For this the driver
uses page_address() which is broken on highmem. Apart from this the
actual calculation of the virtual address is wrong (even without highmem).
So, e.g., for reading it reads bytes from the driver to a wrong address
and returns wrong data, I guess, for writing it would just output random
data to the device.
The proper fix, as suggested by many, is to dynamically map data using
kmap_atomic(page, KM_BIO_SRC_IRQ) / kunmap_atomic(virt). The reason why it
has not been done until now, although I've done some preliminary patches
more than a year ago was that nobody interested in fixing this problem was
able to reliably reproduce it. Now it changed - with the help from
Sebastian Frei (CC'ed) I was able to trigger the PIO path. Thus, I was
also able to test and debug it.
There are 4 cases when PIO is used in dc395x - data-in / -out with and
without scatter-gather. I was able to reproduce and test only data-in with
and without SG. So, the data-out path is still untested, but it is also
somewhat simpler than the data-in. Fredrik Roubert (also CC'ed) also had
PIO triggering on his system, and in his case it was data-out without SG.
It would be great if he could test the attached patch on his system, but
even if he cannot, I would still request to apply the patch and just wait
if anybody cries...
Implementation: I put 2 new functions in scsi_lib.c and their declarations
in scsi_cmnd.h. I exported them without _GPL, although, I don't feel
strongly about that - not many drivers are likely to use them. But there
is at least one more - I want to use them in tmscsim.c. Whether these are
the right files for the functions and their declarations - not sure
either. Actually, they are not scsi-specific, so, might go somewhere
around other scattergather magic? They are not platform specific either,
and most SG functions are defined under arch/*/... As these issues were
discussed previously there were some more routines suggested to manipulate
scattergather buffers, I think, some of them were needed around
crypto code... So, might be a common place reasonable, like
lib/scattergather.c? I am open here.

The init function for the RPA PCI Hotplug driver returns -ENODEV in the
case that no hotplug-capable slots are detected in the system. This is
bad, since hot-capable slots can be added after boot to a purely virtual
POWER partition. This is also bad because DLPAR I/O operations depend
on the rpaphp module.
Change the rpaphp init module to return success for the case of
partitions that own no hotplug-capable slots at boot. Such slots can be

There is a lot of code duplcited between iscsi_tcp
and the upcoming iscsi_iser driver. This patch puts
the duplicated code in a lib. There is more code
to move around but this takes care of the
basics. For iscsi_offload if they use the lib we will
probably move some things around. For example in the
queuecommand we will not assume that the LLD wants
to do queue_work, but it is better to handle that
later when we know for sure what iscsi_offload looks
like (we could probably do this for iscsi_iser though to).
Ideally I would like to get the iscsi_transports modules
to a place where all they really have to do is put data
on the wire, but how to do that will hopefully be more clear
when we see other modules like iscsi_offload. Or maybe
iscsi_offload will not use the lib and it will just be
iscsi_iser and iscsi_tcp and maybe the iscsi_tcp_tgt if that
is allowed in mainline.

The current iscsi_tcp eh is not nicely setup for dm-multipath
and performs some extra task management functions when they
are not needed.
The attached patch:
- Fixes the TMF issues. If a session is rebuilt
then we do not send aborts.
- Fixes the problem where if the host reset fired, we would
return SUCCESS even though we had not really done anything
yet. This ends up causing problem with scsi_error.c's TUR.
- If someone has turned on the userspace nop daemon code to try
and detect network problems before the scsi command timeout
we can now drop and clean up the session before the scsi command
timesout and fires the eh speeding up the time it takes for a
command to go from one patch to another. For network problems
we fail the command with DID_BUS_BUSY so if failfast is set
scsi_decide_disposition fails the command up to dm for it to
try on another path.
- And we had to add some basic iscsi session block code. Previously
if we were trying to repair a session we would retrun a MLQUEUE code
in the queuecommand. This worked but it was not the most efficient
or pretty thing to do since it would take a while to relogin
to the target. For iscsi_tcp/open-iscsi a lot of the iscsi error handler
is in userspace the block code is pretty bare. We will be
adding to that for qla4xxx.

For iscsi boot when going from initramfs to the real root we

iscsid needs to be able to rebuild itself and part of that
process is matching a session running the kernel with the

adds several required iscsi values. If the LLD does not provide
them becuase, login is done in userspace, then the transport

hw iscsi like qla4xxx does not allocate a host per session and
for userspace it is difficult to restart iscsid using the
"iscsi handles" for the session and connection, so this
patch just has the class or userspace allocate the id for
the session and connection.
Note: this breaks userspace and requires users to upgrade to the newest
open-iscsi tools. Sorry about his but open-iscsi is still too new to
say we have a stable user-kernel api and we were not good nough
designers to know that other hw iscsi drivers and iscsid itself would
need such changes. Actually we sorta did but at the time we did not
have the HW available to us so we could only guess.
Luckily, the only tools hooking into the class are the open-iscsi ones
or other tools like iscsitart hook into the open-iscsi engine from
userspace or prgroams like anaconda call our tools so they are not affected.

The manual driver <-> device binding attribute in sysfs doesn't return
the correct value on failure or success of driver_probe_device.
driver_probe_device returns 1 on success (the driver accepted the
device) or 0 on probe failure (when the driver didn't accept the
device but no real error occured). However, the attribute can't just
return 0 or 1, it must return the number of bytes consumed from buf
or an error value. Returning 0 indicates to userspace that nothing
was written (even though the kernel has tried to do the bind/probe and
failed). Returning 1 indicates that only one character was accepted in
which case userspace will re-try the write with a partial string.
A more correct version of driver_bind would return count (to indicate
the entire string was consumed) when driver_probe_device returns 1
and -ENODEV when driver_probe_device returns 0. This patch makes that
change.

It works like this:
Open the file
Read all the contents.
Call poll requesting POLLERR or POLLPRI (so select/exceptfds works)
When poll returns,
close the file and go to top of loop.
or lseek to start of file and go back to the 'read'.
Events are signaled by an object manager calling
sysfs_notify(kobj, dir, attr);
If the dir is non-NULL, it is used to find a subdirectory which
contains the attribute (presumably created by sysfs_create_group).
This has a cost of one int per attribute, one wait_queuehead per kobject,
one int per open file.
The name "sysfs_notify" may be confused with the inotify
functionality. Maybe it would be nice to support inotify for sysfs
attributes as well?

Previously, scatterlist tests didn't write patterned data. Given how many
corner cases are addresed by them, this was a significant gap in Linux-USB
test coverage. Moreover, when peripherals checked for correct data patterns,
false error reports would drown out the true ones.
This adds the pattern on the way OUT from the host, so scatterlist tests can
now be used to uncover bugs like host TX or peripheral RX paths failing for
back-to-back short packets. It's easy enough to get an error there with at
least one of the {DMA,PIO}{RX,TX} code paths, or run into hardware races
that need to be defended against.

Below is a patch to gadgets/net2280.[ch] which adds support for the
net2282 controller. The original code was kindly provided by PLX
Technology, I just merged it with the current net2280 driver in the
kernel. Tested on 2.6.15.6, but only with 2282. I did the merge, so
that the behaviour for the 2280 is unaffected (except for short delays
for extra checks).

Support for net2282 in net2280 driver.
Driver panic when RAID logical volume was present when driver
loaded, or when a RAID logical volume was created on the fly.
This issue was created in due to recent scsi_transport_sas change,
when sas_read_port_mode_page was added into the mptsas drivers
slave_config entry point.
This new API expects that all sdev's to be assocated to an rphy, however
that is not the case for logical volumes, as they are created using
scsi_add_device, instead of sas_rphy_add().

By calling send_sig do_SAK is recursively taking the

In addition I just audited the kernel and this was the only
place where tasklist_lock is taken inside of task_lock.
So this one line change is a general worthwhile cleanup and
it increases our options on how to fix the ptrace_attach races.

As previously reported via Michael Reed, the FC transport took a hit
in 2.6.15 (perhaps a little earlier) when we solved a recursion error.
There are 2 deadlocks occurring:
- With scan and the delete items sharing the same workq, flushing the
workq for the delete code was getting it stalled behind a very long
running scan code path.
- There's a deadlock where scsi_remove_target() has to sit behind
scsi_scan_target() due to contention over the scan_lock().
This patch resolves the 1st deadlock and significantly reduces the
odds of the second. So far, we have only replicated the 2nd deadlock
on a highly-parallel SMP system. More on the 2nd deadlock in a following
email.
This patch reworks the transport to:
- Only use the scsi host workq for scanning
- Use 2 other workq's internally. One for deletions, the other for
scheduled deletions. Originally, we tried this with a single workq,
but the occassional flushes of the scheduled queues was hitting the
second deadlock with a slightly higher frequency. In the future, we'll
look at the LLDD's and the transport to see if we can get rid of this
extra overhead.
- When moving to the other workq's we tightened up some object states
and some lock handling.
- Properly syncs adds/deletes
- minor code cleanups
- directly reference fc_host_attrs, rather than through attribute
macros
- flush the right workq on delayed work cancel failures.
Large kudos to Michael Reed who has been working this issue for the last
month.

When a target is added aic79xx tries to be overly clever: it changes
the command on the fly to TEST UNIT READY and tries to requeue the
original command. Sadly this breaks SCSI compability and of course
the midlayer is getting a bit confused by it.
So we're just removing that bit of code and let the midlayer deal with
it. It's clever enough by now. And the driver code is getting simpler.

Use wait_for_completion_timeout() instead of using a timer (as

That lets me eliminate the sym_eh_wait structure; the struct completion,
the old_done pointer and the to_do flag can be folded into the sym_ucmd
(which overrides the scsi_pointer in scsi_cmnd).
The sym_eh_done() function becomes much simpler as the timeout handling
is done in sym_eh_handler() directly.
The host_lock can be unlocked earlier, and I cache the host in

- use scatterlist I/O
- set number of retries based on the submitted command
This is the last user of non-S/G I/O except for the gdth driver, so
getting this in ASAP and through the scsi tree would be nie to kill

The driver allocates SRQ WQEs size with a power of 2 size both for
Tavor and for memfree. For Tavor, however, the hardware only requires
the WQE size to be a multiple of 16, not a power of 2, and the max
number of scatter-gather allowed is reported accordingly by the
firmware (and this is the value currently returned by
ib_query_device() and ibv_query_device()).
If the max number of scatter/gather entries reported by the FW is used
when creating an SRQ, the creation will fail for Tavor, since the
required WQE size will be increased to the next power of 2, which
turns out to be larger than the device permitted max WQE size (which
is not a power of 2).
This patch reduces the reported SRQ max wqe size so that it can be used
successfully in creating an SRQ on Tavor HCAs.

The pen down IRQ will toggle during each X,Y,Z measurement cycle.
Even though the IRQ is disabled it will be latched and delivered
when after enable_irq. Thus in the IRQ handler we must avoid
starting a new measurement cycle when such an "unwanted" IRQ happens.
Add a get_pendown_state platform function, which will probably
determine this by reading the current GPIO level of the pen IRQ pin.
Move the IRQ reenabling from the SPI RX function to the timer. After
the last power down message the pen IRQ pin is still active for a
while and get_pendown_state would report incorrectly a pen down state.
When suspending we should check the ts->pending flag instead of
ts->pendown, since the timer can be pending regardless of ts->pendown.
Also if ts->pending is set we can be sure that the timer is running,
so no need to rearm it. Similarly if ts->pending is not set we can
be sure that the IRQ is enabled (and the timer is not).

Bugzilla Bug 6299:
A pixel size of 8 bits produces wrong logo colors in x86_64.
The driver has 2 methods for setting the color map, using the protected
mode interface provided by the video BIOS and directly writing to the VGA
registers. The former is not supported in x86_64 and the latter is enabled
only in i386.
Fix by enabling the latter method in x86_64 only if supported by the BIOS.
If both methods are unsupported, change the visual of vesafb to
STATIC_PSEUDOCOLOR.

Remove duplicate call to idr_remove() in ptmx_open.
Error during open can result in call to release_dev() followed by call to
idr_remove(). release_dev already calls idr_remove so the second call can
cause a stack dump in idr_remove()->sub_remove() flagging an attempt to
release an already released entry.
I reproduces this on a machine with a misconfigured X server (attempting to
restart multiple times rapidly) getting the same error as the 1st link
below.
This also seems to be related to:

The stack dump can occur on close (as well as open) as shown
in the 1st instance above, possible from something like:
process A - open (index=0), open fail to out1,
release_dev calls idr_remove (index 0), down(sem) sleeps
process B - open (index=0), open OK (idr allocated)
process A - wake and call idr_remove on index 0
...
process B - close, release_dev, stack dump on idr_remove (index=0)
because entry already removed

NOTE: this is a user-visible change. However:
- The bad code has not appeared in a released kernel
- This code is still marked 'experimental'
- This only affects version-1 superblock, which are not in wide use
- These field are only used (rather than simply reported) by user-space
tools in extemely rare circumstances : after a reshape crashes in the

The PCI spec recommends against drivers playing with a device's PCI

And we actually have users that report that changing it from the
default set by BIOS hurts performance and/or stability for them. On
the other hand, the Mellanox Programmer's Reference Manual recommends
turning it up all the way to the maximum value. Some tests conducted
here in the lab do not show performance improvement from this tuning,
but this might be just me.
As a work-around, make this tuning an option, off by default (safe
value), with an eye towards removing it completely one day if no one

Push translation of static rate to HCA format into low-level drivers,

- Add enum ib_rate to midlayer includes.
- Get rid of static rate translation in IPoIB; just use static rate

- Update mthca driver to translate absolute static rate into the

Speed up SRAM read and write functions if possible by using MMIO
instead of config. cycles. With this change, the post reset signature
done at the end of D3 power change must now be moved before the D3
power change.
IBM reported a problem on powerpc blades during ethtool self test that
was caused by the memory test taking excessively long. Config. cycles
are very slow on powerpc and the memory test can take more than 10
seconds to complete using config. cycles.
David Miller informed me that an earlier version of the patch caused
problems on sparc64 systems with built-in tg3 chips. This version
fixes the problem by excluding all SUN built-in tg3 chips from doing
MMIO SRAM access.
TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when
TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are

This patch enables support for the Sigmatel's STIR421x IrDA chip.
Once patched with Sigmatel's firmware, this chip "almost" follows the
USB-IrDA spec. Thus this patch is against irda-usb.[ch].

This patch integrates the smcinit code into the smsc-ircc driver.
Some laptops have their smsc-ircc chip not properly configured by the
BIOS and needs some preconfiguration. Currently, this can be done from
userspace with smcinit, a utility that comes with the irda-utils
package. It messes with ioports and PCI settings, from userspace. Now
with this patch, if we happen to be on one of the known to be faulty
laptops, we preconfigure the chip from the driver.

We traced this back to local_completions unlocking mad_agent_priv->lock
while still keeping a pointer into local_list. A later call to

sbp2util_mark_command_completed takes a lock which was already taken by
sbp2scsi_complete_all_commands. This is a regression in Linux 2.6.15.
Reported by Kristian Harms at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187394
[ More complete commentary, as response to questions by Andrew: ]
> This changes the call environment for all implementations of
> ->Current_done(). Are they all safe to call under this lock?
Short answer: Yes, trust me. ;-) Long answer:
The done() callbacks are passed on to sbp2 from the SCSI stack along
with each SCSI command via the queuecommand hook. The done() callback
is safe to call in atomic context. So does
Documentation/scsi/scsi_mid_low_api.txt say, and many if not all SCSI
low-level handlers rely on this fact. So whatever this callback does,
it is "self-contained" and it won't conflict with sbp2's internal ORB
list handling. In particular, it won't race with the
sbp2_command_orb_lock.
Moreover, sbp2 already calls the done() handler with
sbp2_command_orb_lock taken in sbp2scsi_complete_all_commands(). I
admit this is ultimately no proof of correctness, especially since this
portion of code introduced the spinlock recursion in the first place and
we didn't realize it since this code's submission before 2.6.15 until
now. (I have learned a lesson from this.)
I stress-tested my patch on x86 uniprocessor with a preemptible SMP
kernel (alas I have no SMP machine yet) and made sure that all code
paths which involve the sbp2_command_orb_lock were gone through multiple
times.

Patch from Pavel Pisa
This patch adds support of i.MX/MX1 SD/MMC controller.
It has been significantly redesigned from the original Sascha Hauer's
version to support scatter-gather DMA, to conform to latest Pierre Ossman's
and Russell King's MMC-SD Linux 2.6.x infrastructure.
The handling of all events has been moved to the softirq context
and is designed with no busy-looping in mind. Unfortunately
some controller bugs has to be overcome by limited looping
about 2-20 usec but these are observed only for initial card
recognition phase.
There are still some missing/missed IRQs problems under heavy load.
Help of somebody with access to the full SDHC design information
is probably necessary.
Regenerated against 2.6.16-git-060402 to solve clash with other patches.

It should be V4L2_TUNER_MODE_LANG1_LANG2. What the code does is check if
we are NTSC and a SAP channel is available. If so, then the msp3400
should switch to standard 0x21 if the user wants to hear the SAP
channel, which is for audio modes LANG2 (aka SAP) and LANG1_LANG2
(bilingual).
In the msp3400 driver STEREO is abused for bilingual in PAL. Bilingual
never worked with NTSC in the past and I decided that I'd better not

but unfortunately some I2C implementations can't transfer data in such
big gulps. Specifically, the pvrusb2 driver has a hard limit of
around 60 bytes, due to the encapsulation there of I2C traffic into

EEPROM support, interrupt handling, statistics gathering, and write
combining management for x86_64.
A note regarding i2c: The Atmel EEPROM hardware we use looks like an
i2c device electrically, but is not i2c compliant at all from a
functional perspective. We tried using the kernel's i2c support to
talk to it, but failed.
Normal i2c devices have a single 7-bit or 10-bit i2c address that they
respond to. Valid 7-bit addresses range from 0x03 to 0x77. Addresses
0x00 to 0x02 and 0x78 to 0x7F are special reserved addresses
(e.g. 0x00 is the "general call" address.) The Atmel device, on the
other hand, responds to ALL addresses. It's designed to be the only
device on a given i2c bus. A given i2c device address corresponds to
the memory address within the i2c device itself.
At least one reason why the linux core i2c stuff won't work for this
is that it prohibits access to reserved addresses like 0x00, which are
really valid addresses on the Atmel devices.

Backlight class attributes are currently easy to implement incorrectly.
Moving certain handling into the backlight core prevents this whilst at the
same time makes the drivers simpler and consistent. The following changes are
included:
The brightness attribute only sets and reads the brightness variable in the
backlight_properties structure.
The power attribute only sets and reads the power variable in the
backlight_properties structure.
Any framebuffer blanking events change a variable fb_blank in the
backlight_properties structure.
The backlight driver has only two functions to implement. One function is
called when any of the above properties change (to update the backlight
brightness), the second is called to return the current backlight brightness
value. A new attribute "actual_brightness" is added to return this brightness
as determined by the driver having combined all the above factors (and any
driver/device specific factors).
Additionally, the backlight core takes care of checking the maximum brightness
is not exceeded and of turning off the backlight before device removal.
The corgi backlight driver is updated to reflect these changes.

If ->setup_func() returns 0, obsolete_checksetup() tries other

a parameter is seted to argv_init[].
Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.

Current cmdlinepart.c uses offset value 0 to specify a continuous
partition. This prevents creating a second partition starting at 0.
For example, I can split 4MB device using "mtdparts=id:2M,2M", but I can
not do "mtdparts=id:2M@2M,2M@0" to swap mtd0 and mtd1.
This patch introduces special OFFSET_CONTINUOUS value for a continuous
partition and allows 0 for offset value.
Also this patch replaces 0xffffffff with UINT_MAX for SIZE_REMAINING.

This ugly hack add support for Siemens MC45 PCMCIA GPRS card (which is
identical to Possio GCC, and which is offered by one of our local GPRS
providers). Card has unfortunate feature that after poweron oxcf950 chip
is fully powered and works, but attached MC45 modem is powered down :-(
There is a special sequence (which takes 1 sec :-( ) to poweron MC45 (and
after MC45 powers on, it takes more than 2 secs until firmware fully
boots...) which needs to be executed after all powerons.
I'm really not familiar with PCMCIA subsystem, so I have no idea whether I
should issue request_region() on rest of oxcf950 address range (0-7 is
UART, 8-F are special configuration registers), or how this should be
better integrated with PM system and so on - I just put it in same place
where another hack already lived...
Card uses 18.432MHz XTAL, so to get it to work you must add lines below to
the /etc/pcmcia/serial.opts.

(1) A DMA transfer size of 0x10000 was not being written
as 0x0000 in the PRDs. Fixed.
(1) The DEV_IRQ interrupt cause bit happens spuriously
during EDMA operation, and was not being ignored by the driver.
This led to various "drive busy" errors being reported,
with associated unpredictable behaviour. Fixed.
(2) If a SATA or PCI interrupt was received with no outstanding
command, the interrupt handler still attempted to invoke
ata_qc_complete(), triggering assert()/BUG_ON() behaviour
elsewhere in libata. Fixed.
The driver still has issues with confusion after error-recovery,
but should now be reliable in the absence of drive errors.
I will be looking more into the error-handling bugs next.

Add a field to the host_set called 'flags' (was host_set_flags changed

Add a ->mode_filter() hook to allow drivers to filter modes
Add docs for mode_filter and set_mode
Filter according to simplex state
Filter cable in core
This provides the needed framework to support all the mode rules found
in the PATA world. The simplex filter deals with 'to spec' simplex DMA
systems found in older chips. The cable filter avoids duplicating the
same rules in each chip driver with PATA. Finally the mode filter is
neccessary because drive/chip combinations have errata that forbid
certain modes with some drives or types of ATA object.
Drive speed setup remains per channel for now and the filters now use
the framework Tejun put into place which cleans them up a lot from the
older libata-pata patches.

This is the minimal patch set to enable the current code to be used with
a controller following SFF (ie any PATA and early SATA controllers)
safely without crashes if there is no BMDMA area or if BMDMA is not
assigned by the BIOS for some reason.
Simplex status is recorded but not acted upon in this change, this isn't
a problem with the current drivers as none of them are for simplex
hardware. A following diff will deal with that.
The flags in the probe structure remain ->host_set_flags although Jeff
asked me to rename them, simply because the rename would break the usual
Linux rules that old code should break when there are changes. not
compile and run and then blow up/eat your computer/etc. Renaming this

the check is incorrect, since ds (WQE stride) is always a power-of-2
(although the max_desc_size may not be).
In Tavor, however, WQE stride and desc_size are the same, and are not
necessarily power-of-2. The check was really for the WQE stride (and
it Tavor, we use max_desc_size for the stride).

I'm not really certain what the thinking was but the code obviously wanted to
walk processes other than just those in it's session, for purposes of do_SAK.
Just walking those tasks that don't have a session assigned sounds at the very
least incomplete.
So modify the code to kill everything in the session and anything else that
might have the tty open. Hopefully this helps if the do_SAK functionality is

When using verion-0.90 superblock, we convert the version to 0.91 while the
conversion is happening so that an old kernel will refuse the assemble the

When starting an array we check for an incomplete reshape and restart the

It allocated new stripe_heads for the next chunk-wide-stripe in the target
geometry, marking them STRIPE_EXPANDING.
Then it finds which stripe heads in the old geometry can provide data needed
by these and marks them STRIPE_EXPAND_SOURCE. This causes stripe_handle to
read all blocks on those stripes.
Once all blocks on a STRIPE_EXPAND_SOURCE stripe_head are read, any that are
needed are copied into the corresponding STRIPE_EXPANDING stripe_head. Once a
STRIPE_EXPANDING stripe_head is full, it is marks STRIPE_EXPAND_READY and then

We need to allow that different stripes are of different effective sizes, and
use the appropriate size. Also, when a stripe is being expanded, we must
block any IO attempts until the stripe is stable again.
Key elements in this change are:
- each stripe_head gets a 'disk' field which is part of the key,
thus there can sometimes be two stripe heads of the same area of
the array, but covering different numbers of devices. One of these
will be marked STRIPE_EXPANDING and so won't accept new requests.
- conf->expand_progress tracks how the expansion is progressing and
is used to determine whether the target part of the array has been
expanded yet or not.

Before a RAID-5 can be expanded, we need to be able to expand the stripe-cache
data structure.
This requires allocating new stripes in a new kmem_cache. If this succeeds,
we copy cache pages over and release the old stripes and kmem_cache.
We then allocate new pages. If that fails, we leave the stripe cache at it's
new size. It isn't worth the effort to shrink it back again.
Unfortuanately this means we need two kmem_cache names as we, for a short
period of time, we have two kmem_caches. So they are raid5/%s and
raid5/%s-alt

The remainder of this batch implements raid5 reshaping. Currently the only
shape change that is supported is added a device, but it is envisioned that
changing the chunksize and layout will also be supported, as well as changing
the level (e.g. 1->5, 5->6).
The reshape process naturally has to move all of the data in the array, and so
should be used with caution. It is believed to work, and some testing does
support this, but wider testing would be great for increasing my confidence.
You will need a version of mdadm newer than 2.3.1 to make use of raid5 growth.
This is because mdadm need to take a copy of a 'critical section' at the
start of the array incase there is a crash at an awkward moment. On restart,
mdadm will restore the critical section and allow reshape to continue.
I hope to release a 2.4-pre by early next week - it still needs a little more
polishing.
This patch:
Previously the array of disk information was included in the raid5 'conf'
structure which was allocated to an appropriate size. This makes it awkward
to change the size of that array. So we split it off into a separate
kmalloced array which will require a little extra indexing, but is much easier
to grow.

Before removing a snapshot, wait for the completion of any kcopyd jobs using
it.
Do this by maintaining a count (nr_jobs) of how many outstanding jobs each
kcopyd_client has.
The snapshot destructor first unregisters the snapshot so that no new kcopyd
jobs (created by writes to the origin) will reference that particular
snapshot. kcopyd_client_destroy() is now run next to wait for the completion
of any outstanding jobs before the snapshot exception structures (that those

dm-mirror has potential data corruption problem: while on-disk log shows
that all disk contents are in-sync, actual contents of the disks are not
synchronized. This problem occurs if initial recovery (synching) is
interrupted and resumed.
Attached patch fixes this problem.
Background:
rh_dec() changes the region state from RH_NOSYNC (out-of-sync) to RH_CLEAN
(in-sync), which results in the corresponding bit of clean_bits being set.
This is harmful if on-disk log is used and the map is removed/suspended
before the initial sync is completed. The clean_bits is written down to
the on-disk log at the map removal, and, upon resume, it's read and copied
to sync_bits. Since the recovery process refers to the sync_bits to find a
region to be recovered, the region whose state was changed from RH_NOSYNC
to RH_CLEAN is no longer recovered.
If you haven't applied dm-raid1-read-balancing.patch proposed in dm-devel
sometimes ago, the contents of the mirrored disk just corrupt silently. If
you have, balanced read may get bogus data from out-of-sync disks.
The patch keeps RH_NOSYNC state unchanged. It will be changed to
RH_RECOVERING when recovery starts and get reclaimed when the recovery
completes. So it doesn't leak the region hash entry.
Description:
Keep RH_NOSYNC state unchanged when I/O on the region completes.
rh_dec() changes the region state from RH_NOSYNC (out-of-sync) to RH_CLEAN
(in-sync), which results in the corresponding bit of clean_bits being set.
This is harmful if on-disk log is used and the map is removed/suspended

If you haven't applied dm-raid1-read-balancing.patch proposed in dm-devel

you have, balanced read may get bogus data from out-of-sync disks.
The RH_NOSYNC region will be changed to RH_RECOVERING when recovery starts
on the region and get reclaimed when the recovery completes. So it doesn't
leak the region hash entry.
Alasdair said:
I've analysed the relevant part of the state machine and I believe that
the patch is correct.

side-effect of holding onto memory unnecessarily for long periods of time
under certain workloads - but better that than corrupting data.)

When a snapshot becomes invalid, s->valid is set to 0. In this state, a
snapshot can no longer be accessed.
When s->lock is acquired, before doing anything else, s->valid must be checked
to ensure the snapshot remains valid.
This patch eliminates some races (that may cause panics) by adding some
missing checks. At the same time, some unnecessary levels of indentation are
removed and snapshot invalidation is moved into a single function that always
generates a device-mapper event.

The siblings "list" is used unsafely at the moment.
Firstly, only the element on the list being changed gets locked (via the
snapshot lock), not the next and previous elements which have pointers that
are also being changed.
Secondly, if you have two or more snapshots and write to the same chunk a
second time before every snapshot has finished making its private copy of the
data, if you're unlucky, _origin_write() could attempt its list_merge() and
dereference a 'last' pointer to a pending_exception structure that has just
been freed.
Analysis reveals that the list is actually only there for reference counting.
If 5 pending_exceptions are needed in origin_write, then the 5 are joined
together into a 5-element list - without a separate list head because there's
nowhere suitable to store it. As the pending_exceptions complete, they are
removed from the list one-by-one and any contents of origin_bios get moved
across to one of the remaining pending_exceptions on the list. Whichever one
is last is detected because list_empty() is then true and the origin_bios get
submitted.
The fix proposed here uses an alternative reference counting mechanism by
choosing one of the pending_exceptions as primary and maintaining an atomic
counter there.

Say you have several snapshots of the same origin and then you issue a write
to some place in the origin for the first time.
Before the device-mapper snapshot target lets the write go through to the
underlying device, it needs to make a copy of the data that is about to be
overwritten. Each snapshot is independent, so it makes one copy for each
snapshot.
__origin_write() loops through each snapshot and checks to see whether a copy
is needed for that snapshot. (A copy is only needed the first time that data
changes.)
If a copy is needed, the code allocates a 'pending_exception' structure
holding the details. It links these together for all the snapshots, then
works its way through this list and submits the copying requests to the kcopyd
thread by calling start_copy(). When each request is completed, the original
pending_exception structure gets freed in pending_complete().
If you're very unlucky, this structure can get freed *before* the submission
process has finished walking the list.
This patch:
1) Creates a new temporary list pe_queue to hold the pending exception
structures;
2) Does all the bookkeeping up-front, then walks through the new list
safely and calls start_copy() for each pending_exception that needed it;
3) Avoids attempting to add pe->siblings to the list if it's already
connected.
[NB This does not fix all the races in this code. More patches will follow.]

A set of 3 small bugfixes, all of which are related to bogus return values
of fb colormap-setting functions.
First, fb_alloc_cmap returns -1 if memory allocation fails. This is a hard
condition to reproduce since you'd have to be really low on memory, but from
studying the contexts in which it is called, I think this function should be
returning a negative errno, and the -1 will be seen as an EPERM. Switching it
to -ENOMEM makes sense.
Second, the store_cmap function which is called for writes to
/sys/class/graphics/fb0/color_map returns 0 for success, but it should be
returning the count of bytes written since its return value ends up in
userspace as the result of the write() syscall.
Third, radeonfb returns 1 instead of a negative errno when FBIOPUTCMAP is
called with an oversized colormap. This is seen in userspace as a return
value of 1 from the ioctl() syscall with errno left unchanged. A more
useful return value would be -EINVAL.

The kernel's implementation of notifier chains is unsafe. There is no
protection against entries being added to or removed from a chain while the
chain is in use. The issues were discussed in this thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2
We noticed that notifier chains in the kernel fall into two basic usage
classes:
"Blocking" chains are always called from a process context
and the callout routines are allowed to sleep;
"Atomic" chains can be called from an atomic context and
the callout routines are not allowed to sleep.
We decided to codify this distinction and make it part of the API. Therefore
this set of patches introduces three new, parallel APIs: one for blocking
notifiers, one for atomic notifiers, and one for "raw" notifiers (which is
really just the old API under a new name). New kinds of data structures are
used for the heads of the chains, and new routines are defined for
registration, unregistration, and calling a chain. The three APIs are
explained in include/linux/notifier.h and their implementation is in
kernel/sys.c.
With atomic and blocking chains, the implementation guarantees that the chain
links will not be corrupted and that chain callers will not get messed up by
entries being added or removed. For raw chains the implementation provides no
guarantees at all; users of this API must provide their own protections. (The
idea was that situations may come up where the assumptions of the atomic and
blocking APIs are not appropriate, so it should be possible for users to
handle these things in their own way.)
There are some limitations, which should not be too hard to live with. For
atomic/blocking chains, registration and unregistration must always be done in
a process context since the chain is protected by a mutex/rwsem. Also, a
callout routine for a non-raw chain must not try to register or unregister
entries on its own chain. (This did happen in a couple of places and the code
had to be changed to avoid it.)
Since atomic chains may be called from within an NMI handler, they cannot use
spinlocks for synchronization. Instead we use RCU. The overhead falls almost
entirely in the unregister routine, which is okay since unregistration is much
less frequent that calling a chain.
Here is the list of chains that we adjusted and their classifications. None
of them use the raw API, so for the moment it is only a placeholder.
ATOMIC CHAINS
-------------
arch/i386/kernel/traps.c: i386die_chain

BLOCKING CHAINS
---------------
arch/powerpc/platforms/pseries/reconfig.c: pSeries_reconfig_chain
arch/s390/kernel/process.c: idle_chain
arch/x86_64/kernel/process.c idle_notifier
drivers/base/memory.c: memory_chain

net/ipv4/devinet.c: inetaddr_chain
It's possible that some of these classifications are wrong. If they are,
please let us know or submit a patch to fix them. Note that any chain that
gets called very frequently should be atomic, because the rwsem read-locking
used for blocking chains is very likely to incur cache misses on SMP systems.
(However, if the chain's callout routines may sleep then the chain cannot be
atomic.)

It seems to me that the today's wireless-2.6 git contains bcm43xx which
does not free txb's correctly, if I understand it right.
Consider a situation where a txb with two skb's is sent down.
The dma_tx_fragment will save the pointer to meta->txb of the first
fragment. If fragments are freed in order, ieee80211_txb_free frees both
skb's when the first fragment is processed. This may result in reuse
of the second skb's memory.
This danger is rather remote, but it seems to me that the patch
below not only fixes the problem, but also makes the code simpler,
which is good, right?

- After we unregister a kobject, wait for our kobject release method
to call complete(). This causes us to wait until the kobject
reference count reaches 0. Otherwise, a task accessing the EDAC
sysfs interface can hold the reference count above 0 until after the
EDAC module has been unloaded. When the reference count finally
drops to 0, this will result in an attempt to call our release
method inside the EDAC module after the module has already been
unloaded.
This isn't the best fix, since a process can get stuck sleeping forever
uninterruptibly if the user does the following:
rmmod my_module < /sys/my_sysfs/file
I'll go back and implement a better fix later. However this should
be ok for now.
- Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather

The following patches add drivers for the Siemens Gigaset 3070 family of ISDN
DECT PABXes connected via USB, either directly or over a DECT link using a
Gigaset M105 or compatible DECT data adapter. The devices are integrated as
ISDN adapters within the isdn4linux framework, supporting incoming and
outgoing voice and data connections, and also as tty devices providing access
to device specific AT commands.
Supported devices include models 3070, 3075, 4170, 4175, SX205, SX255, and
SX353 from the Siemens Gigaset product family, as well as the technically
identical models 45isdn and 721X from the Deutsche Telekom Sinus series.
Supported DECT adapters are the Gigaset M105 data and the technically
identical Gigaset USB Adapter DECT, Sinus 45 data 2, and Sinus 721 data (but
not the Gigaset M34 and Sinus 702 data which advertise themselves as CDC-ACM
devices).
These drivers have been developed over the last four years within the
SourceForge project http://sourceforge.net/projects/gigaset307x/. They are
being used successfully in several installations for dial-in Internet access
and for voice call switching with Asterisk.
This is our second attempt at submitting these drivers, taking into account
the comments we received to our first submission on 2005-12-11.
The patch set adds three kernel modules:
- a common module "gigaset" encapsulating the common logic for
controlling the PABX and the interfaces to userspace and the
isdn4linux subsystem.
- a connection-specific module "bas_gigaset" which handles
communication with the PABX over a direct USB connection.
- a connection-specific module "usb_gigaset" which does the same
for a DECT connection using the Gigaset M105 USB DECT adapter.
We also have a module "ser_gigaset" which supports the Gigaset M101 RS232 DECT
adapter, but we didn't judge it fit for inclusion in the kernel, as it does
direct programming of a i8250 serial port. It should probably be rewritten as
a serial line discipline but so far we lack the neccessary knowledge about
writing a line discipline for that.
The drivers have been working with kernel releases 2.2 and 2.4 as well as 2.6,
and although we took efforts to remove the compatibility code for this
submission, it probably still shows in places. Please make allowances.
This patch:
Prepare the kernel build infrastructure for addition of the Gigaset ISDN
drivers. It creates a Makefile and Kconfig file for the Gigaset driver and
hooks them into those of the isdn4linux subsystem. It also adds a MAINTAINERS
entry for the driver.
This patch depends on patches 2 to 9 of the present set, as without the actual
source files, activating the options added here will cause the kernel build to
fail.

tlclk calls register_chrdev() and permits register_chrdev() to allocate the
major, but it promptly forgets what that major was. So if there's no hardware
present you still get "telco_clock" appearing in /proc/devices and, I assume,
an oops reading /proc/devices if tlclk was a module.
Fix.
Mark, I'd suggest that that we not call register_chrdev() until _after_ we've
established that the hardware is present.

Add full driver model support for the IPMI driver. It links in the proper
bus and device support.
It adds an "ipmi" driver interface that has each BMC discovered by the
driver (as a device). These BMCs appear in the devices/platform directory.
If there are multiple interfaces to the same BMC, the driver should
discover this and will only have one BMC entry. The BMC entry will have
pointers to each interface device that connects to it.
The device information (statistics and config information) has not yet been
ported over to the driver model from proc, that will come later.
This work was based on work by Yani Ioannou. I basically rewrote it using
that code as a guide, but he still deserves credit :).

Almost all users of the table addresses from the EFI system table want
physical addresses. So rather than doing the pa->va->pa conversion, just keep
physical addresses in struct efi.
This fixes a DMI bug: the efi structure contained the physical SMBIOS address
on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap()
on a virtual address on ia64.
This is essentially the same as an earlier patch by Matt Tolentino:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2
except that this changes all table addresses, not just ACPI addresses.
Matt's original patch was backed out because it caused MCAs on HP sx1000
systems. That problem is resolved by the ioremap() attribute checking added
for ia64.

Pass the size, not a pointer to the size, to efi_mem_attribute_range().
This function validates memory regions for the /dev/mem read/write/mmap paths.
The pointer allows arches to reduce the size of the range, but I think that's
unnecessary complexity. Simplifying it will let me use
efi_mem_attribute_range() to improve the ia64 ioremap() implementation.

Venki, author of cpufreq_ondemand, came up with a neater way to remove the
initialiser code from the main loop of my code and out to the point when the
governor is actually initialised.
Not only does it look but it also feels cleaner, plus its simpler to
understand. It also saves a bunch of pointless conditional statements in the
main loop.

All these changes should make cpufreq_conservative safe in regards to the x86
for_each_cpu cpumask.h changes and whatnot.
Whilst making it safe a number of pointless for loops related to the cpu
mask's were removed. I was never comfortable with all those for loops,
especially as the iteration is over the same data again and again for each
CPU you had in a single poll, an O(n^2) outcome to frequency scaling.
The approach I use is to assume by default no CPU's exist and it sets the
requested_freq to zero as a kind of flag, the reasoning is in the source ;)
If the CPU is queried and requested_freq is zero then it initialises the
variable to current_freq and then continues as if nothing happened which
should be the same net effect as before?

The sensible approach to making conservative less responsive than ondemand :)
As mentioned in patch [1/4]. We do not want conservative to shoot through

Since the conservative govenor was released its codebase has drifted from the
the direction and updates that have been applied to the ondemand govornor.
This patch addresses the lack of updates in that period and brings
conservative back up to date. The resulting diff file between
cpufreq_ondemand.c and cpufreq_conservative.c is now much smaller and shows
more clearly the differences between the two.
Another reason to do this is ages ago, knowingly, I did a piss poor attempt
at making conservative less responsive by knocking up
DEF_SAMPLING_RATE_LATENCY_MULTIPLIER by two orders of magnitude. I did fix
this ages ago but in my dis-organisation I must have toasted the diff and
left it the way it was. About two weeks ago a user contacted me saying he
was having problems with the conservative governor with his AMD Athlon XP-M
2800+ as /sys/devices/system/cpu/cpu0/cpufreq/conservative showed
sampling_rate_min 9950000
sampling_rate_max 1360065408

Initramfs initrd images do not need a ramdisk device, so remove this
restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also
without ramdisk device there's no need for "dry run", so initramfs unpacks
much faster.
People using cramfs, squashfs, or gzipped ext2/minix initrd images are
probably smart enough not to turn off ramdisk support by accident.

Remove the assumption that driver_register() returns the number of devices

zorro_module_init() used the device count to automatically unregister and

but has been broken for some time because zorro_register_driver() returned
either a negative error or a positive count (never zero). So it could only

This patch causes the network interface to respond to P_Key change
events correctly. As a result, you'll see a child interface in the
"RUNNING" state (netif_carrier_on()) only when the corresponding P_Key
is configured by the SM. When SM removes a P_Key, the "RUNNING" state
will be disabled for the corresponding network interface. To
implement this, I added IB_EVENT_PKEY_CHANGE event handling. To
prevent flushing the device before the device is open by the "delay
open" mechanism, I added an additional device flag called
IPOIB_FLAG_INITIALIZED.
This also prevents the child network interface from trying to join to
multicast groups until the PKEY is configured. We used to get error
messages like:
ib0.f2f2: couldn't attach QP to multicast group ff12:401b:f2f2:0:0:0:ffff:ffff
in this case. To fix this, I just check IPOIB_FLAG_OPER_UP flag in
ipoib_set_mcast_list().

Since the SCSI midlayer is moving towards entirely getting rid of
commands with use_sg == 0, we should treat this case as an exception.
Therefore, change the IB SRP initiator to create a fake scatterlist
for these commands with sg_init_one(). This simplifies the flow of
DMA mapping and unmapping, since SRP can just use dma_map_sg() and
dma_unmap_sg() unconditionally, rather than having to choose between
the dma_{map,unmap}_sg() and dma_{map,unmap}_single() variants.

When a request is aborted because of a signal, we currently stop the request
via csh, but we do not wait for the interrupt of csh in any case. We free the
request structure and therefore when the interrupt for the csh operation is
presented, the request object is no longer valid and an invalid callback
pointer is used.
To fix this wait until the interrupt for csh arrives and until
wait_event_interruptible() does not return -ERESTARTSYS.

This avoids searching a linear list on every call to dasd_ioctl(), and allows

moving the check for bdev->bd_disk->private_data from the individual functions
to dasd_ioctl. (I think it can't actually every be NULL, but let's keep that

libata core is being changed to disallow port/device disable on lower
layers. However, some LLDDs (sata_mv) directly disable port on
command failure. This patch makes ata_exec_internal() check whether a
port got disabled after an internal command. If it is, AC_ERR_SYSTEM
is added to err_mask and the port gets re-enabled.
As internal command failure results in device disable for drivers
which don't implement newer reset/EH callbacks, this change results in
no behavior change for single device per port controllers. For
slave-possible LLDDs which disable port on command failure, (1) such
drivers don't exist currently, (2) issuing command to the other device
of once-disabled port shouldn't result in catastrophe even if such
driver exists. So, this should be enough as a temporary measure.

bridge. So hotplug PCI slots under the nested PCI-to-PCI bridge would
not be detected. For example, if the system has the ACPI namespace
like below, hotplug slots woule not be detected.
Device (PCI0) { /* Root bridge */
Name (_HID, "PNP0A03")
Device (P2PA) { /* PCI-to-PCI bridge */

Device (P2PB) { /* PCI-to-PCI bridge */

These patches add generic dock event handling to acpiphp. If there are
pci devices that need to be inserted/removed after the dock event, the
event notification will be handed down to the normal pci hotplug event
handler in acpiphp so that new bridges/devices can be enumerated.
Because some dock stations do not have pci bridges or pci devices that
need to be inserted after a dock, acpiphp will remain loaded to handle
dock events even if no hotpluggable pci slots are discovered.
You probably need to have the pci=assign-busses kernel parameter enabled
to use these patches, and you may not allow ibm_acpi to handle docking
notifications and use this patch.
This patch incorporates feedback provided by many.

"In some cases, especially on modern laptops with a lot of PCI and cardbus
bridges, we're unable to assign correct secondary/subordinate bus numbers
to all cardbus bridges due to BIOS limitations unless we are using
"pci=assign-busses" boot option." -- Ivan Kokshaysky (from a patch comment)
Without it, Cardbus cards inserted are never seen by PCI because the parent
PCI-PCI Bridge of the Cardbus bridge will not pass and translate Type 1 PCI
configuration cycles correctly and the system will fail to find and
initialise the PCI devices in the system.
Reference: PCI-PCI Bridges: PCI Configuration Cycles and PCI Bus Numbering:
http://www.science.unitn.it/~fiorella/guidelinux/tlk/node72.html
The reason for this is that:
``All PCI busses located behind a PCI-PCI bridge must reside between the
secondary bus number and the subordinate bus number (inclusive).''
"pci=assign-busses" makes pcibios_assign_all_busses return 1 and this
turns on PCI renumbering during PCI probing.
Alan suggested to use DMI automatically set assign-busses on problem systems.
The only question for me was where to put it. I put it directly before
scanning PCI bus into pcibios_scan_root() because it's called from legacy,
acpi and numa and so it can be one place for all systems and configurations
which may need it.
AMD64 Laptops are also affected and fixed by assign-busses, and the code is
also incuded from arch/x86_64/pci/ that place will also work for x86_64
kernels, I only ifdef'-ed the x86-only Laptop in this example.
Affected and known or assumed to be fixed with it are (found by googling):
* ASUS Z71V and L3s
* Samsung X20
* Compaq R3140us and all Compaq R3000 series laptops with TI1620 Controller,
also Compaq R4000 series (from a kernel.org bugreport)
* HP zv5000z (AMD64 3700+, known that fixup_parent_subordinate_busnr fixes it)
* HP zv5200z
* IBM ThinkPad 240
* An IBM ThinkPad (1.8 GHz Pentium M) debugged by Pavel Machek
gives the correspondig message which detects the possible problem.
* MSI S260 / Medion SIM 2100 MD 95600
The patch also expands the "try pci=assign-busses" warning so testers will
help us to update the DMI table.

Current SHPCHP driver doesn't care about the confliction between
hotplug operation via sysfs and hotplug operation via attention
button. So if those ware conflicted, slot could be an unexpected
state.
This patch changes SHPCHP driver to handle slot state properly. With
this patch, slot events are handled according to the current slot
state as shown at the Table below.
Table. Slot States and Event Handling
=========================================================================
Slot State Event and Action
=========================================================================
STATIC - Go to POWERON state if user initiates
(Slot enabled, insertion request via sysfs
Slot disabled) - Go to POWEROFF state if user initiates removal
request via sysfs
- Go to BLINKINGON state if user presses
attention button when the slot is disabled
- Go to BLINKINGOFF state if user presses
attention button when the slot is enabled
The event handler of SHPCHP driver is unnecessarily very complex. In
addition, current event handler can only a fixed number of events at
the same time, and some of events would be lost if several number of
events happened at the same time.
This patch simplify the event handler by using 'work queue', and it
also fix the above-mentioned issue.

Agreed, looks like an accident. The patch [1] originally came from Kip
Walker (Broadcom back then) between 2.6.0-test3 and 2.6.0-test4. As I
recall it was supposed to fix an issue with with PCI aborts being
signalled by the PCI bridge of the Broadcom BCM1250 family of SOCs when
probing behind pci_scan_bridge. It is undeseriable to disable
PCI_BRIDGE_CTL_MASTER_ABORT in pci_{read,write)_config_* and the
behaviour wasn't considered a bug in need of a workaround, so this was
put in probe.c.
I don't have an affected system at hand, so can't really test but I
propose something like the below patch.
[1] http://www.linux-mips.org/git?p=linux.git;a=commit;h=599457e0cb702a31a3247ea6a5d9c6c99c4cf195

very small, both in terms of number of lines of code and memory
consumption.

Don't free transmit buffers until the whole set of transmit descriptors
has been marked as done. Otherwise, we risk freeing a skb before the
whole transmit is done.
This changes the transmit completion handling from incremental to a
two pass algorithm. First pass scans and records the start of the last
done descriptor, second cleans up until that point.

When we stop allocating percpu memory for not-possible CPUs we must not touch

is to test cpu_possible() or to use for_each_cpu().
This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very
few instances of this bug, if any. But the patch converts lots of open-coded
test to use the preferred helper macros.

efficient with a 6-byte cache. We could even do with a 3-byte cache, but at
the cost of additional arithmetics arguably not worth the spared 3 bytes.

When grabbing composite video with Iomega Buz, the stock driver will
prevent grabbing from the same input twice in a row, forcing the user to
switch inputs before anything useful can be grabbed again. It is caused by
some optimization code in the input selection parts, and triggered by the
saa7111_command() executing cmd 0. The attached patch will remedy this by
disabling cmd 0 altogether; a fix that has no found negative effects on the
rest of the code. In fact, saa7110.c does the exact same thing.

This is version 20 of the Wireless Extensions. This is the
completion of the RtNetlink work I started early 2004, it enables the
full Wireless Extension API over RtNetlink.
Few comments on the patch :
o totally driver transparent, no change in drivers needed.
o iwevent were already RtNetlink based since they were created
(around 2.5.7). This adds all the regular SET and GET requests over
RtNetlink, using the exact same mechanism and data format as iwevents.
o This is a Kconfig option, as currently most people have no
need for it. Surprisingly, patch is actually small and well
encapsulated.
o Tested on SMP, attention as been paid to make it 64 bits clean.
o Code do probably too many checks and could be further
optimised, but better safe than sorry.
o RtNetlink based version of the Wireless Tools available on
my web page for people inclined to try out this stuff.

The current code follows the spec but uses an overlong delay. This would
be great if the hardware did. Several vendors however forget the D7
pulldown. Fortunately 0xFF isnt a sane reset state so we can use it to
skip detection as is done in drivers/ide. (ie this is a tested solution
over a long time)

set_page_count usage outside mm/ is limited to setting the refcount to 1.
Remove set_page_count from outside mm/, and replace those users with
init_page_count() and set_page_refcounted().
This allows more debug checking, and tighter control on how code is allowed
to play around with page->_count.

sg increments the refcount of constituent pages in its higher order memory
allocations when they are about to be mapped by userspace. This is done so
the subsequent get_page/put_page when doing the mapping and unmapping does not
free the page.
Move over to the preferred way, that is, using compound pages instead. This
fixes a whole class of possible obscure bugs where a get_user_pages on a
constituent page may outlast the user mappings or even the driver.

SLAB_NO_REAP is documented as an option that will cause this slab not to be
reaped under memory pressure. However, that is not what happens. The only
thing that SLAB_NO_REAP controls at the moment is the reclaim of the unused
slab elements that were allocated in batch in cache_reap(). Cache_reap()
is run every few seconds independently of memory pressure.
Could we remove the whole thing? Its only used by three slabs anyways and
I cannot find a reason for having this option.
There is an additional problem with SLAB_NO_REAP. If set then the recovery
of objects from alien caches is switched off. Objects not freed on the
same node where they were initially allocated will only be reused if a
certain amount of objects accumulates from one alien node (not very likely)
or if the cache is explicitly shrunk. (Strangely __cache_shrink does not
check for SLAB_NO_REAP)
Getting rid of SLAB_NO_REAP fixes the problems with alien cache freeing.

All accessor's different methods are now selected with C code and unused
ones statically optimized away at compile time instead of being selected
with #if's and #ifdef's. This has many advantages such as allowing the
compiler to validate the syntax of the whole code, making it cleaner and
easier to understand, and ultimately allowing people to define
configuration symbols in terms of variables if they really want to
dynamically support multiple bus configurations at the same time (with
the unavoidable performance cost).
