drm/dp_mst: Reprobe path resources in CSN handler
We used to punt off reprobing path resources to the link address probe
work, but now that we handle CSNs asynchronously from the driver's HPD
handling we can do whatever the heck we want from the CSN!
So, reprobe the path resources from drm_dp_mst_handle_conn_stat(). Also,
get rid of the path resource reprobing code in
drm_dp_check_and_send_link_address() since it's needlessly complicated
when we already reprobe path resources from
drm_dp_handle_link_address_port(). And finally, teach
drm_dp_send_enum_path_resources() to return 1 on PBN changes so we know
if we need to send another hotplug or not.
This fixes issues where we've indicated to userspace that a port has
just been connected, before we actually probed it's available PBN -
something that results in unexpected atomic check failures.

drm/dp_mst: Use full_pbn instead of available_pbn for bandwidth checks
DisplayPort specifications are fun. For a while, it's been really unclear to us what available_pbn actually does. There's a somewhat vague explanation in the DisplayPort spec (starting from 1.2) that partially explains it: The minimum payload bandwidth number supported by the path. Each node updates this number with its available payload bandwidth number if its payload bandwidth number is less than that in the Message Transaction reply. So, it sounds like available_pbn represents the smallest link rate in use between the source and the branch device. Cool, so full_pbn is just the highest possible PBN that the branch device supports right? Well, we assumed that for quite a while until Sean Paul noticed that on some MST hubs, available_pbn will actually get set to 0 whenever there's any active payloads on the respective branch device. This caused quite a bit of confusion since clearing the payload ID table would end up fixing the available_pbn value. So, we just went with that until commit |

drm/i915/execlists: Enable timeslice on partial virtual engine dequeue
If we stop filling the ELSP due to an incompatible virtual engine request, check if we should enable the timeslice on behalf of the queue. This fixes the case where we are inspecting the last->next element when we know that the last element is the last request in the execution queue, and so decided we did not need to enable timeslicing despite the intent to do so!

drm/i915: be more solid in checking the alignment
The alignment is u64, and yet is_power_of_2() assumes unsigned long,

drm/exynos: Fix cleanup of IOMMU related objects
Store the IOMMU mapping created by the device core of each Exynos DRM
sub-device and restore it when the Exynos DRM driver is unbound. This
fixes IOMMU initialization failure for the second time when a deferred
probe is triggered from the bind() callback of master's compound DRM
driver. This also fixes the following issue found using kmemleak

ARM: SoC fixes
We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was
a miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing for
a while, so a few updates of that.
... and the usual collection of smaller fixes to various platforms.

Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Olof Johansson:
"We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was a
miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing
for a while, so a few updates of that.
... and the usual collection of smaller fixes to various platforms"

io_uring: fix lockup with timeouts
There is a recipe to deadlock the kernel: submit a timeout sqe with a linked_timeout (e.g. test_single_link_timeout_ception() from liburing), and SIGKILL the process. Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it during io_put_free() to cancel the linked timeout. Probably, the same can happen with another io_kill_timeout() call site, that is io_commit_cqring().

powerpc fixes for 5.6 #4
One fix for a recent regression to our breakpoint/watchpoint code.
Another fix for our KUAP support, this time a missing annotation in a rarely
used path in signal handling.
A fix for our handling of a CPU feature that effects the PMU, when booting
guests in some configurations.
A minor fix to our linker script to explicitly include the .BTF section.
Thanks to:
Christophe Leroy, Desnes A. Nunes do Rosario, Leonardo Bras, Naveen N. Rao,
Ravi Bangoria, Stefan Berger.

linux-kselftest-5.6-rc5
This Kselftest update for Linux 5.6-rc5 consists of a cleanup patch to undo changes to global .gitignore that added selftests/lkdtm objects and add them to a local selftests/lkdtm/.gitignore. Summary of Linus's comments on local vs. global gitignore scope: - Keep local gitignore patterns in local files. - Put only global gitignore patterns in the top-level gitignore file. Local scope keeps things much better separated. It also incidentally means that if a directory gets renamed, the gitignore file continues to work unless in the case of renaming the actual files themselves that are named in the gitignore. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEPZKym/RZuOCGeA/kCwJExA0NQxwFAl5izzwACgkQCwJExA0N QxxGpBAArJzDZp02xR8QfCrFyY8qXsFOEkFhjc22jNx6nl5cMb6nRUFbDszCEq05 0QmVb1Hfh+tsz5PXtcugC/pfulUPmho8mN6sXEfwjqcyQFj/4y94wfpRig/KqMXj ECV3zjm39wb3iAh5PQxrymzWrv0ZmmKphpi9fpUDGCGEoG7cemsfIfwkRKBUFBOa O1PTz0sLbhMQs02N/5mwJk0WGxtjFQ5ShM5EQh1nzxgA3ObXcjybMarusWhVx2SN oO3UR7hrJTTozgcisiK8xz8SP4Hq1i6E11HE06PfE52YsVAEwNjsXf0KushKxWHo sm9B4dtkcy1qM+JfbVRKS9LPSyKiGEDUzmqKQy2dgVUX2K3ScJ6scXNnLSnPbqjX OPjaMTkIYUyxZ4Z4vn8a9+b3xc6fLxi9aiaxqfpdfbIJyiIyGhAvVwS1zWa1AUqW /mEPRE9BplpQTthkBHNHCdwG1NGAzV/gwtZHDeuiy/BdtlQNjzqr0vh26sTN1z0M NPMAl2Teqv2NOfOcHvhphyNXuuW9IE96ZoYDyFz6ZF6jN+J9jZtWpHRCnnd7dK9Q fLwbJUZtfr7v0r/1jsYag0MPJlyBaW1rvuEH9rpbF+Z/+ODrDPiAt05bPmrk9BYO hwmvcWsCalQUlOYQdhpEUFJgHoWoy4GJMMI3ao+xCooXiAylTt0= =8sYZ -----END PGP SIGNATURE----- Merge tag 'linux-kselftest-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull kselftest update from Shuah Khan: "This consists of a cleanup patch to undo changes to global .gitignore that added selftests/lkdtm objects and add them to a local selftests/lkdtm/.gitignore.

RISC-V Fixes for 5.6-rc5
This tag contains a handful of fixes that I would like to target for 5.6:
* A pair of fixes to module loading, which we hope solve the last of the issues
with module text being loaded too sparsely for our call relocations.
* A Kconfig fix that disallows selecting memory models not supported by NOMMU.
* A series of Kconfig updates to ease selecting the drivers necessary to run on
QEMU's virt platform.
* DTS updates for SiFive's HiFive Unleashed.
* A fix to our seccomp support that avoids mangling restartable syscalls.

It can be reproduce in the linux mainline by the program:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <sys/ioctl.h>
#include <linux/vt.h>
struct tiocl_selection {
unsigned short xs; /* X start */
unsigned short ys; /* Y start */
unsigned short xe; /* X end */
unsigned short ye; /* Y end */
unsigned short sel_mode; /* selection mode */
};
#define TIOCL_SETSEL 2
struct tiocl {
unsigned char type;
unsigned char pad;
struct tiocl_selection sel;
};
int main()
{
int fd = 0;
const char *dev = "/dev/char/4:1";
struct vt_consize v = {0};
struct tiocl tioc = {0};
fd = open(dev, O_RDWR, 0);
v.v_rows = 3346;
ioctl(fd, VT_RESIZEX, &v);
tioc.type = TIOCL_SETSEL;
ioctl(fd, TIOCLINUX, &tioc);
return 0;
}
When resize the screen, update the 'vc->vc_size_row' to the new_row_size,
but when 'set_origin' in 'vgacon_set_origin', vgacon use 'vga_vram_base'
for 'vc_origin' and 'vc_visible_origin', not 'vc_screenbuf'. It maybe
smaller than 'vc_screenbuf'. When TIOCLINUX, use the new_row_size to calc
the offset, it maybe larger than the vga_vram_size in vgacon driver, then
bad access.
Also, if set an larger screenbuf firstly, then set an more larger
screenbuf, when copy old_origin to new_origin, a bad access may happen.
So, If the screen size larger than vga_vram, resize screen should be
failed. This alse fix CVE-2020-8649 and CVE-2020-8647.
Linus pointed out that overflow checking seems absent. We're saved by
the existing bounds checks in vc_do_resize() with rather strict
limits:
if (cols > VC_RESIZE_MAXCOL || lines > VC_RESIZE_MAXROW)
return -EINVAL;
