bochs_pci_probe() allocates the DRM device with devm_drm_dev_alloc(),
which registers a devres action to drop the initial DRM device reference
on driver detach or probe failure.
The error path currently calls drm_dev_put() manually. If probe then
returns an error, devres will run the registered release action and put
the same device again, after the first put may already have released it.
Return the probe error directly and let devres own the final put.

The engine state size reported to GuC via ADS should only include the

that comes after it in the context image. The GuC uses this size to
overwrite the engine state in the LRC on watchdog resets and we don't

pf_migration_mmio_save() and pf_migration_mmio_restore() initialize a
local VF-specific MMIO view via xe_mmio_init_vf_view() but then pass
>->mmio (the PF base) to all xe_mmio_read32()/xe_mmio_write32()
calls instead of the local &mmio. This causes the PF own SW flag
registers to be saved/restored rather than the target VF registers,
silently corrupting migration state.
Use the VF MMIO view for all register accesses, matching the correct
pattern used in pf_clear_vf_scratch_regs().

PTR_ERR() returns a negative value, so comparing against the positive
EAGAIN is always true for ERR_PTR(-EAGAIN), causing pf_migration_consume()
to bail out instead of continuing to the remaining GTs. On multi-GT
platforms this can skip GTs that already have data ready.
Compare against -EAGAIN to match the intent (and the following line
that correctly uses -EAGAIN). While at it, gate PTR_ERR() with
IS_ERR().

When media GT is disabled via configfs, there is no allocation for
media_gt, which is kept as NULL. In such scenario,
intel_hdcp_gsc_check_status() results in a kernel pagefault error due to
>->uc.gsc being evaluated as an invalid memory address.
Fix that by introducing a NULL check on media_gt and bailing out early
if so.
While at it, also drop the NULL check for gsc, since it can't be NULL if
media_gt is not NULL.
v2:
- Get address for gsc only after checking that gt is not NULL.
(Shuicheng)
- Drop the NULL check for gsc. (Shuicheng)

When preparing the panel, it seems that it always expects commands to be
transferred in LP mode. However, the disable function removes the
MIPI_DSI_MODE_LPM flag, and no other function re-adds it.
As the unprepare function contains no DSI commands, re-adding the flag
just after disabling the panel should be safe. Add the code re-adding
the flag after the two commands for disabling the panel are sent.

When xa_alloc_cyclic() failed in etnaviv_sched_push_job(), the error
path skipped drm_sched_entity_push_job(). This is a violation of the DRM
scheduler contract, as once a job has been armed with drm_sched_job_arm(),
it must be pushed with drm_sched_entity_push_job(). From the DRM
scheduler documentation,
"""
drm_sched_job_arm() is a point of no return since it initializes the
fences and their sequence number etc. Once that function has been called,
you *must* submit it with drm_sched_entity_push_job() and cannot simply
abort it by calling drm_sched_job_cleanup().
"""
Fix this by splitting the fence ID allocation into two phases: first,
alloc an xarray slot before arming the job (which can fail), then fill in
the actual fence with xa_store() after arming. This way, allocation
failures are handled before the job is armed, and once armed, the job is
always pushed to the scheduler.
This also fixes a double call to drm_sched_job_cleanup(), as both
etnaviv_sched_push_job() and its caller would call it on failure.

When the damage area resulting from a dirty memory range spans a single
scanline, the width of the rectangle is calculated dynamically because it
may not coincide with the framebuffer width.
If the dirty range ends exactly at the end of the scanline, the `bit_end`
variable is incorrectly assigned a 0 value, which results in a bogus clip
rectangle where the x2 coordinate is 0. This prevents the dirty scanline
from being flushed to the hardware.
Change the calculation of the `bit_end` value to fix the x2 coordinate
value in the above edge case.

Consolidation of empty_zero_page declarations broke boot on sh.
sh stores its initial boot parameters in a page reserved in
arch/sh/kernel/head_32.S. Before commit 6215d9f447 ("arch, mm:
consolidate empty_zero_page") this page was referenced in C code
as an array and after that commit it is referenced as a pointer.
This causes wrong code generation and boot hang.
Declare boot_params_page as an array to fix the issue.

If pinned initialization of drm::Device::Data fails, it calls
drm::Device::release via drm_dev_put. This materializes a reference to
&drm::Device, but it's not fully constructed yet, because initializing
`data` failed. It should not be dropped either. Instead, if pinned
initialization fails, make sure drm::Device::release isn't called.

Currently need_futex_hash_allocate_default() depends on strict pthread
semantics, abusing CLONE_THREAD. This breaks the non-concurrency
assumptions when doing the mm->futex_ref pcpu allocations, leading to
bugs[0] when sharing the mm in other ways; ie:
BUG: KASAN: slab-use-after-free in futex_hash_put
... where the +1 bias can end up on a percpu counter that mm->futex_ref
no longer points at.
Loosen the check to cover any CLONE_VM clone, except vfork(). Excluding
vfork keeps the existing paths untouched (no overhead), and we can't
race in the first place: either the parent is suspended and the child
runs alone, or mm->futex_ref is already allocated from an earlier

Pull io_uring fixes from Jens Axboe:
- Remove dead struct io_buffer_list member
- Fix for incrementally consumed buffers with recvmsg multishot, which
requires a minimum value left in a buffer for any receive for the
headers. If there's still a bit of buffer left but it's smaller than
that value, then userspace will see a spurious -EFAULT returned in
the CQE
- Locking fix for the DEFER_TASKRUN retry list, which otherwise could
race with fallback cancelations. If the task is exiting with
task_work left in both the normal and retry list AND the exit cleanup
races with the task running task work, then entries could either be
doubly completed or lost

into excessive polling and triggering warnings around that

Commit 2e8a1acea8 ("arm64: signal: Improve POR_EL0 handling to
avoid uaccess failures") delayed the write to POR_EL0 in
rt_sigreturn to avoid spurious uaccess failures. This change however
relies on the poe_context frame record being present: on a system
supporting POE, calling sigreturn without a poe_context record now
results in writing arbitrary data from the kernel stack into POR_EL0.
Fix this by adding a __valid_fields member to struct
user_access_state, and zeroing the struct on allocation.
restore_poe_context() then indicates that the por_el0 field is valid
by setting the corresponding bit in __valid_fields, and
restore_user_access_state() only touches POR_EL0 if there is a valid
value to set it to. This is in line with how POR_EL0 was originally
handled; all frame records are currently optional, except
fpsimd_context.
To ensure that __valid_fields is kept in sync, fields (currently
just por_el0) are now accessed via accessors and prefixed with __ to
discourage direct access.

For 4K pages, the early kernel mapping may use 2MB block entries but the
kernel segments are only 64KB aligned. Segment boundaries that fall
within a 2MB block therefore require a PTE table so that different
attributes can be applied on either side of the boundary.
KERNEL_SEGMENT_COUNT still correctly counts the five permanent kernel
VMAs registered by declare_kernel_vmas(). However, since commit
5973a62efa ("arm64: map [_text, _stext) virtual address range
non-executable+read-only"), the early mapper also maps [_text, _stext)
separately from [_stext, _etext). This adds one more early-only split
and can require one more page-table page than the existing
EARLY_SEGMENT_EXTRA_PAGES allowance reserves.
Increase the 4K-page early mapping allowance by one page to cover that
additional split.
