Compare the sampled clock values instead of their addresses. Comparing
addresses leaves the samples unsorted, preventing the code from discarding
the minimum and maximum samples.

intel_engine_user.c checks CONFIG_DRM_I915_SELFTESTS before running
the engine UABI isolation check. Kconfig defines DRM_I915_SELFTEST,
without the trailing "S", and the rest of i915 uses
CONFIG_DRM_I915_SELFTEST.
Because CONFIG_DRM_I915_SELFTESTS is not backed by any Kconfig symbol,
the IS_ENABLED() test is always false. Use the existing selftest symbol
so the debug/selftest guarded path can be reached when selftests are
enabled.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the Kconfig definition and the inconsistent
guard in intel_engine_user.c.

Avoid using intel_context_put() before intel_context_init() in
execlists_create_virtual() as the kref_put() inside would lead
to NULL deref on the IOCTL path when sched_engine allocation fails.
Discovered using AI-assisted static analysis confirmed by
Intel Product Security.

After a GPU reset the HWSP is zeroed, so previously completed
requests appear incomplete. If such a request is picked up during
reset_rewind() and marked guilty, i915_request_set_error_once()
returns early (fence already signaled), leaving fence.error without
a fatal error code. The subsequent __i915_request_skip() then hits:
```
GEM_BUG_ON(!fatal_error(rq->fence.error))
```
Fixes a kernel BUG observed on Sandy Bridge (Gen6) during
heartbeat-triggered engine resets.
```
kernel BUG at drivers/gpu/drm/i915/i915_request.c:556!
RIP: __i915_request_skip+0x15e/0x1d0 [i915]

```
Guard __i915_request_skip() with i915_request_signaled(), if the
fence is already signaled, the ring content is committed and there
is nothing left to skip.

The display reset only happens from the full reset path. We must
therefore force execlist submission to always take the full reset
path and not the per-engine reset path. Currently the display
reset tests are in fact not testing display resets at all on
platforms using execlist submission. Ring submission and GuC
submission always take the full path anyway.
Also disable the engine reset inside __intel_gt_set_wedged() so
that we simulate the intel_gt_gpu_reset_clobbers_display() behavior
as closely as possible also when taking the full wedge path.
The slight race between the separate intel_display_reset_test()
calls in the overall reset path is harmless. kms_busy will keep
the modparam fixed during the test, and even if someone were to
fiddle with the modparam manually nothing bad should happen if
the calls return different values.

Only i915 uses the pending_fb_pin counter to potentially whack
the GPU harder if the display gets nuked during a GPU reset.
Move the atomic counter into the i915 specific bits of code, so
that we don't need to worry about on the display side.
For some reason the overlay code kept the pending_fb_pin counter
elevated for longer than just for the pin, but from now on it'll
just cover the actual pinning part.

Stop returning the "is there a display?" status from
intel_display_reset_prepare(). I plan to move the pending_fb_pin
into the i915 code, so I need to make that determination already
before intel_display_reset_prepare() is called. Add a new
intel_display_reset_supported() function for that.
v2: Also check display!=NULL for mock tests

A use-after-free / refcount underflow is possible when the heartbeat
worker and intel_engine_park_heartbeat() race to release the same
engine->heartbeat.systole request.
The heartbeat worker reads engine->heartbeat.systole and calls
i915_request_put() on it when the request is complete, but clears
the pointer in a separate, non-atomic step. Concurrently, a request
retirement on another CPU can drop the engine wakeref to zero, triggering
__engine_park() -> intel_engine_park_heartbeat(). If the heartbeat
timer is pending at that point, cancel_delayed_work() returns true and
intel_engine_park_heartbeat() reads the stale non-NULL systole pointer
and calls i915_request_put() on it again, causing a refcount underflow:

Fix this by replacing the non-atomic pointer read + separate clear with
xchg() in both racing paths. xchg() is a single indivisible hardware
instruction that atomically reads the old pointer and writes NULL. This
guarantees only one of the two concurrent callers obtains the non-NULL
pointer and performs the put, the other gets NULL and skips it.

Since the PCI registers are used from both i915 display and core, move
intel_pci_config.h to include/drm/intel/pci_config.h. Drop the intel_
prefix from the name to reduce tautology.
With this, we can drop the corresponding xe display compat header.

Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
system_unbound_wq should be the default workqueue so as not to enforce
locality constraints for random work whenever it's not required.
This patch continues the effort to refactor worqueue APIs, which has
begun with the change introducing new workqueues:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
The old system_unbound_wq will be kept for a few release cycles.

The underscore prefixed masked field helper names aren't great. Rename
them REG_MASKED_FIELD(), REG_MASKED_FIELD_ENABLE(), and
REG_MASKED_FIELD_DISABLE(). This is more in line with the existing
REG_FIELD_PREP() etc. helpers, and using "field" instead of "bit" is
more accurate for the functionality.
This is done with:
sed -i 's/_MASKED_FIELD/REG_MASKED_FIELD/g' $(git grep -wl _MASKED_FIELD)
sed -i 's/_MASKED_BIT_ENABLE/REG_MASKED_FIELD_ENABLE/g' $(git grep -wl _MASKED_BIT_ENABLE)
sed -i 's/_MASKED_BIT_DISABLE/REG_MASKED_FIELD_DISABLE/g' $(git grep -wl _MASKED_BIT_DISABLE)
with some manual indentation fixes on top.

Since it's now possible to use _MASKED_BIT_ENABLE() and
_MASKED_BIT_DISABLE() in the array initializer, switch to them. This
allows us to remove __MASKED_FIELD() macro.

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.

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*'.

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.

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 *".

In order to be able to use only vma_flags_t in vm_area_desc we must adjust
shmem file setup functions to operate in terms of vma_flags_t rather than
vm_flags_t.
This patch makes this change and updates all callers to use the new
functions.
No functional changes intended.

Patch series "Unload linux/kernel.h", v5.
kernel.h hosts declarations that can be placed better. This series
decouples kernel.h with some explicit and implicit dependencies; also,
moves tracing functionality to a new independent header.
This patch (of 6):
The macro was introduced in 1994, v1.0.4, for stacks protection. Since
that, people found better ways to protect stacks, and now the macro is
only used by i915 selftests. Move it to a local header and drop from the
kernel.h.

CONFIG_RANDSTRUCT may reorder structure fields, which makes positional
initializers unsafe. The i915 GT debugfs tables were using positional
initializers for `struct intel_gt_debugfs_file`, and on configs where
the layout differs (e.g., presence/absence of the `.eval` callback),
this can lead to fields being initialized incorrectly and trigger
randstruct warnings such as:
```
drivers/gpu/drm/i915/gt/intel_gt_debugfs.c:75:51: note: randstruct:
casting between randomized structure pointer types (constructor)
```
Switch all the GT debugfs file arrays to designated initializers. This
binds each value to the intended member regardless of structure
reordering or optional members and removes the warning while preserving
the intended initialization. Also drops the '&' from
intel_eval_slpc_support so .eval receives the function pointer directly.
No functional change, only initialization style is updated.

Switch error injection testing from i915_inject_probe_failure
to ALLOW_ERROR_INJECTION. Here taken out calls to
i915_inject_probe_failure and changed to use
ALLOW_ERROR_INJECTION for the same functions.
Below functions are dropped from testing since I
couldn't hit those at module bind time, testing
these would just fail the tests. To include these
in test would need to find way to cause resetting in i915
which would trigger these:
intel_gvt_init
intel_wopcm_init
intel_uc_fw_upload
intel_gt_init with expected -EIO (-EINVAL is tested)
lrc_init_wa_ctx
intel_huc_auth
guc_check_version_range
intel_uc_fw_fetch
uc_fw_xfer
__intel_uc_reset_hw
guc_enable_communication
uc_init_wopcm
..and all stages of __force_fw_fetch_failures
