Wei Liu edd20cb693 Revert "mshv: expose the scrub partition hypercall" 
This reverts commit 36d6cbb621.

Calling this as a passthrough hypercall leaves the VM in an inconsistent
state. Revert before it is released.

Anirudh Rayabharam (Microsoft) 622d68772d mshv: add arm64 support for doorbell & intercept SINTs 
On x86, the HYPERVISOR_CALLBACK_VECTOR is used to receive synthetic
interrupts (SINTs) from the hypervisor for doorbells and intercepts.
There is no such vector reserved for arm64.

On arm64, the hypervisor exposes a synthetic register that can be read
to find the INTID that should be used for SINTs. This INTID is in the
PPI range.

To better unify the code paths, introduce mshv_sint_vector_init() that
either reads the synthetic register and obtains the INTID (arm64) or
just uses HYPERVISOR_CALLBACK_VECTOR as the interrupt vector (x86).

Anirudh Rayabharam (Microsoft) 5a674ef871 mshv: refactor synic init and cleanup 
Rename mshv_synic_init() to mshv_synic_cpu_init() and
mshv_synic_cleanup() to mshv_synic_cpu_exit() to better reflect that
these functions handle per-cpu synic setup and teardown.

Use mshv_synic_init/cleanup() to perform init/cleanup that is not per-cpu.
Move all the synic related setup from mshv_parent_partition_init.

Move the reboot notifier to mshv_synic.c because it currently only
operates on the synic cpuhp state.

Move out synic_pages from the global mshv_root since its use is now
completely local to mshv_synic.c.

This is in preparation for adding more stuff to mshv_synic_init().

No functional change.

Linus Torvalds 32a92f8c89 Convert more 'alloc_obj' cases to default GFP_KERNEL arguments 
This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

Linus Torvalds 323bbfcf1e Convert 'alloc_flex' family to use the new default GFP_KERNEL argument 
This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.

As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

Linus Torvalds bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument 
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

Linus Torvalds e19e1b480a add default_gfp() helper macro and use it in the new *alloc_obj() helpers 
Most simple allocations use GFP_KERNEL, and with the new allocation
helpers being introduced, let's just take advantage of that to simplify
that default case.

It's a numbers game:

    git grep 'alloc_obj(' |
	sed 's/.*\(GFP_[_A-Z]*\).*/\1/' |
	sort | uniq -c | sort -n | tail

shows that about 90% of all those new allocator instances just use that
standard GFP_KERNEL.

Those helpers are already macros, and we can easily just make it be the
default case when the gfp argument is missing.

And yes, we could do that for all the legacy interfaces too, but let's
keep it to just the new ones at least for now, since those all got
converted recently anyway, so this is not any "extra" noise outside of
that limited conversion.

And, in fact, I want to do this before doing the -rc1 release, exactly
so that we don't get extra merge conflicts.

Linus Torvalds fa5c82f4d2 slab.h: disable completely broken overflow handling in flex allocations 
Commit 69050f8d6d ("treewide: Replace kmalloc with kmalloc_obj for
non-scalar types") started using the new allocation helpers, and in the
process showed that they were completely non-working.

The overflow logic in overflows_flex_counter_type() is completely the
wrong way around, and that broke __alloc_flex() completely.  By chance,
the resulting code was then such a mess that clang generated
sufficiently garbage code that objtool warned about it all.  Which made
it somewhat quicker to narrow things down.

While fixing overflows_flex_counter_type() would presumably fix this
all, I'm excising the whole broken overflow logic from __alloc_flex(),
because we don't want that kind of code in basic allocation functions
anyway.

That (no longer) broken overflows_flex_counter_type() thing needs to be
inserted into the actual __set_flex_counter() logic in the unlikely case
that we ever want this at all.  And made conditional.

   to select fields using 'perf report''s -F/-fields, e.g.:
 
     'perf report --fields overhead,type'
 
 - Add 'perf test' regression tests for Data-type profiling with
   C and Rust workloads.
 
 - Fix srcline printing with inlines in callchains, make sure this has
   coverage in 'perf test'.
 
 - Fix printing of leaf IP in LBR callchains.
 
 - Fix display of metrics without sufficient permission in 'perf stat'.
 
 - Print all machines in 'perf kvm report -vvv', not just the host.
 
 - Switch from SHA-1 to BLAKE2s for build ID generation, remove SHA-1
   code.
 
 - Fix 'perf report's histogram entry collapsing with '-F' option.
 
 - Use system's cacheline size instead of a hardcoded value in 'perf
   report'.
 
 - Allow filtering conversion by time range in 'perf data'.
 
 - Cover conversion to CTF using 'perf data' in 'perf test'.
 
 - Address newer glibc const-correctness (-Werror=discarded-qualifiers)
   issues.
 
 - Fixes and improvements for ARM's CoreSight support, simplify ARM SPE
   event config in 'perf mem', update docs for 'perf c2c' including the
   ARM events it can be used with.
 
 - Build support for generating metrics from arch specific python script,
   add extra AMD, Intel, ARM64 metrics using it.
 
 - Add AMD Zen 6 events and metrics.
 
 - Add JSON file with OpenHW Risc-V CVA6 hardware counters.

Coccinelle cannot overwrite debug files.

Benjamin Philip bb1c9ccf74 scripts: coccicheck: warn on unset debug file 
coccicheck prints debug logs to stdout unless a debug file has been set.
This makes it hard to read coccinelle's suggested changes, especially
for someone new to coccicheck.

From this commit, we warn about this behaviour from within the script on
an unset debug file. Explicitly setting the debug file to /dev/null
suppresses the warning while keeping the default.

Kees Cook 69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types 
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

This silently drops all command-line options on the restarted skeleton.

Reset optind to 1 at the restart label so options are re-parsed.

David Carlier f892f9f994 tools/sched_ext: scx_userland: fix data races on shared counters 
The stats thread reads nr_vruntime_enqueues, nr_vruntime_dispatches,
nr_vruntime_failed, and nr_curr_enqueued concurrently with the main
thread writing them, with no synchronization.

Use __atomic builtins with relaxed ordering for all accesses to these

Linus Torvalds d79526b895 spi: Fixes for v7.0 merge window 
There's a relatively large but ultimately simple fix for spidev here
 which addresses some ABBA races by simplifying down to just using a
 single lock, it's not clear to me that there was ever any benefit in
 having the two separate locks in the first place.
 
 We also have simple missing error check fix in in the wpcm-fiu driver.

Linus Torvalds 68010e7b3d Tracing fixes for 7.0: 
- Fix possible dereference of uninitialized pointer
 
   When validating the persistent ring buffer on boot up, if the first
   validation fails, a reference to "head_page" is performed in the
   error path, but it skips over the initialization of that variable.
   Move the initialization before the first validation check.
 
 - Fix use of event length in validation of persistent ring buffer
 
   On boot up, the persistent ring buffer is checked to see if it is
   valid by several methods. One being to walk all the events in the
   memory location to make sure they are all valid. The length of the
   event is used to move to the next event. This length is determined
   by the data in the buffer. If that length is corrupted, it could
   possibly make the next event to check located at a bad memory location.
 
   Validate the length field of the event when doing the event walk.
 
 - Fix function graph on archs that do not support use of ftrace_ops
 
   When an architecture defines HAVE_DYNAMIC_FTRACE_WITH_ARGS, it means
   that its function graph tracer uses the ftrace_ops of the function
   tracer to call its callbacks. This allows a single registered callback
   to be called directly instead of checking the callback's meta data's
   hash entries against the function being traced.
 
   For architectures that do not support this feature, it must always
   call the loop function that tests each registered callback (even if
   there's only one). The loop function tests each callback's meta data
   against its hash of functions and will call its callback if the
   function being traced is in its hash map.
 
   The issue was that there was no check against this and the direct
   function was being called even if the architecture didn't support it.
   This meant that if function tracing was enabled at the same time
   as a callback was registered with the function graph tracer, its
   callback would be called for every function that the function tracer
   also traced, even if the callback's meta data only wanted to be
   called back for a small subset of functions.
 
   Prevent the direct calling for those architectures that do not support
   it.
 
 - Fix references to trace_event_file for hist files
 
   The hist files used event_file_data() to get a reference to the
   associated trace_event_file the histogram was attached to. This
   would return a pointer even if the trace_event_file is about to
   be freed (via RCU). Instead it should use the event_file_file()
   helper that returns NULL if the trace_event_file is marked to be
   freed so that no new references are added to it.
 
 - Wake up hist poll readers when an event is being freed
 
   When polling on a hist file, the task is only awoken when a hist
   trigger is triggered. This means that if an event is being freed
   while there's a task waiting on its hist file, it will need to wait
   until the hist trigger occurs to wake it up and allow the freeing
   to happen. Note, the event will not be completely freed until all
   references are removed, and a hist poller keeps a reference. But
   it should still be woken when the event is being freed.

Linus Torvalds 233a0c0f44 eCryptfs fixes for 7.0-rc1 
The set of eCryptfs patches for the 7.0-rc1 merge window consists of
 cleanups that are not intended to have any functional changes:
 - Comment typo fixes
 - Removal of an unused function declaration
 - Use strscpy() instead of the deprecated strcpy()
 - Use string copying helpers instead of memcpy() and manually
   terminating strings
 
 The patches have all spent time in linux-next and they do not regress
 the tests in the ecryptfs-utils tree.

Koichiro Den 8c1f92ca8b NTB: ntb_transport: Use seq_file for QP stats debugfs 
The ./qp*/stats debugfs file for each NTB transport QP is currently
implemented with a hand-crafted kmalloc() buffer and a series of
scnprintf() calls. This is a pre-seq_file style pattern and makes future
extensions easy to truncate.

Convert the stats file to use the seq_file helpers via
DEFINE_SHOW_ATTRIBUTE(), which simplifies the code and lets the seq_file
core handle buffering and partial reads.

Koichiro Den 6a4b50585d NTB: ntb_transport: Fix too small buffer for debugfs_name 
The buffer used for "qp%d" was only 4 bytes, which truncates names like
"qp10" to "qp1" and causes multiple queues to share the same directory.

Enlarge the buffer and use sizeof() to avoid truncation.

yangqixiao 21fbdc4d0b ntb/ntb_tool: correct sscanf format for u64 and size_t in tool_peer_mw_trans_write 
The sscanf() call in tool_peer_mw_trans_write() uses "%lli:%zi" to parse
user input into 'u64 addr' and 'size_t wsize'. This is incorrect:

 - "%lli" expects a signed long long *, but 'addr' is u64 (unsigned).
   Input like "0x8000000000000000" is misinterpreted as negative,
   leading to corrupted address values.

 - "%zi" expects a signed ssize_t *, but 'wsize' is size_t (unsigned).
   Input of "-1" is successfully parsed and stored as SIZE_MAX
   (e.g., 0xFFFFFFFFFFFFFFFF), which may cause buffer overflows
   or infinite loops in subsequent memory operations.

Fix by using format specifiers that match the actual variable types:
 - "%llu" for u64 (supports hex/decimal, standard for kernel u64 parsing)
 - "%zu" for size_t (standard and safe; rejects negative input)
