Patchsets in this merge:
- The 2 patch series "selftests/mm: clean up build output and verbosity"
from Li Wang removes some noise from the MM selftests build out.
- The 3 patch series "mm: Free contiguous order-0 pages efficiently"
from Ryan Roberts speeds up the freeing of a batch of 0-order pages by
first scanning them for coalescing opportunities. This is applicable to
vfree() and to the releasing of frozen pages.
- The 11 patch series "mm/damon: introduce DAMOS failed region quota
charge ratio" from SeongJae Park addresses a DAMOS usability issue: The
DAMOS quota often exhausts prematurely because it charges for all memory
attempted, causing slow and inconsistent performance when actions fail
on unreclaimable memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing
- The 8 patch series "selftests/cgroup: improve zswap tests robustness
and support large page sizes" from Li Wang fixes various spurious
failures and improves the overall robustness of the cgroup zswap
selftests.
- The 3 patch series "fix MAP_DROPPABLE not supported errno" from
Anthony Yznaga fixes an issue in the mlock selftests on arm32.
- The 2 patch series "mm: huge_memory: clean up defrag sysfs with
shared" from Breno Leitao does some maintenance work in the huge_memory
code.
- The 3 patch series "treewide: fixup gfp_t printks" from Brendan
Jackman uses the special vprintf() gfp_t conversion in various places.
- The 6 patch series "mm: Fix vmemmap optimization accounting and
initialization" from Muchun Song fixes several bugs in the vmemmap
optimization, mainly around incorrect page accounting and memmap
initialization in the DAX and memory hotplug paths. It also fixes
pageblock migratetype initialization and struct page initialization for
ZONE_DEVICE compound pages.
- The 4 patch series "mm/damon: repost non-hotfix reviewed patches in
damon/next tree" from is a sprinkle of unrelated minor bugfixes for
DAMON.
- The 3 patch series "mm: remove page_mapped()" from David Hildenbrand
remove this function from the tree, replacing it with folio_mapped().
- The 10 patch series "mm/damon: let DAMON be paused and resumed" from
SeongJae Park permits DAMON to be paused and resumed without losing its
current state.
- The 3 patch series "kasan: hw_tags: Disable tagging for stack and
page-tables" from Muhammad Usama Anjum simplifies and speeds up kasan by
removing its ineffective tagging of stacks and page tables.
- The 7 patch series "mm/damon/reclaim,lru_sort: monitor all system rams
by default" from SeongJae Park simplifies deployment on diverse hardware
like NUMA systems by updating DAMON_RECLAIM and DAMON_LRU_SORT to
automatically monitor the physical address range covering all System RAM
areas by default, replacing the overly restrictive behavior that only
targeted the single largest memory block to save on negligible overhead.
- The 2 patch series "mm/damon/sysfs: document filters/ directory as
deprecated" from SeongJae Park updates some DAMON docs.
- The 8 patch series "mm: use spinlock guards for zone lock" from Dmitry
Ilvokhin switches zone->lock handling over to using the guard()
mechanisms.
- The 2 patch series "mm/filemap: tighten mmap_miss hit accounting" from
fujunjie fixes a flaw where the mmap_miss counter over-credited page
cache hits during fault-arounds and page-fault retries. This results in
significant reduction of redundant synchronous mmap readahead I/O,
drastically cutting down execution time and gigabytes read for sparse
random or strided memory access workloads.
- The 2 patch series "selftests/cgroup: Fix false positive failures in
test_percpu_basic" from Li Wang fixes a couple of false-positives in the
cgroup kmem selftests.
- The 2 patch series "mm/damon/reclaim: support monitoring intervals
auto-tuning" from SeongJae Park adds a new parameter to DAMON permitting
DAMON_RECLAIM to automatically tune DAMON's sampling and aggregation
intervals.
- The 2 patch series "mm/damon/stat: add kdamond_pid parameter" from
SeongJae Park chnges DAMON_STAT to provide the pid of its kdamond.
- The 2 patch series "mm/kmemleak: dedupe verbose scan output" from
Breno Leitao removes large amounts of duplicated backtraces from the
verbose-mode kmemleak output.
- The 8 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)"
from David Hildenbrand reduces our use of CONFIG_HAVE_BOOTMEM_INFO_NODE,
with a view to removing it entirely in a later series.
- The 2 patch series "mm/damon: validate min_region_size to be power of
2" from Liew Rui Yan prevents users from passing a non-power-of-2 value
of `addr_unit', as this later results in undesirable behavior.
- The 2 patch series "mm: document read_pages and simplify usage" from
Frederick Mayle does as claimed.
- The 3 patch series "tools/mm/page-types: Fix misc bugs" from Ye Liu
fixes three issues in tools/mm/page-types.c.
- The 4 patch series "mm: misc cleanups from __GFP_UNMAPPED series" from
Brendan Jackman implements several cleanups in the page allocator and
related code.
- The 12 patch series "mm, swap: swap table phase IV: unify allocation"
from Kairui Song unifies the allocation and charging of anon and shmem
swap in folios, provides better synchronization, consolidates the
metadata management, hence dropping the static array and map, and
improves performance.
- The 28 patch series "mm/damon: introduce data attributes monitoring"
from SeongJae Park extends DAMON for monitoring general data attributes
other than accesses.
- The 5 patch series "mm/vmalloc: free unused pages on vrealloc()
shrink" from Shivam Kalra implements the TODO in vrealloc() to unmap and
free unused pages when shrinking across a page boundary.
- The 3 patch series "mm/damon: documentation and comment fixes" from
niecheng does as advertised.
- The 3 patch series "remove mmap_action success, error hooks" from
Lorenzo Stoakes eliminates custom hooks from mmap_action by removing the
problematic success_hook which allowed drivers to improperly access
uninitialized VMAs. It replaces the error_hook with a simple error-code
field and updates the memory char driver accordingly.
- The 14 patch series "mm/damon: minor improvements for code readability
and tests" from SeongJae Park implements minor improvements in code
readability and tests for DAMON.
- The 2 patch series "mm/damon: fix macro arguments and clarify quota
goals doc" from Maksym Shcherba does those things.
- The 2 patch series "userfaultfd: merge fs/userfaultfd.c into
mm/userfaultfd.c" from Mike Rapoport performs that code movement.
- The 15 patch series "mm/mglru: improve reclaim loop and dirty folio"
from Kairui Song and others cleans up and slightly improves MGLRU's
reclaim loop and dirty writeback handling. Large performance
improvements are measured.
- The 3 patch series "use vma locks for proc/pid/{smaps|numa_maps}
reads" from Suren Baghdasaryan uses per-vma locks when reading
/proc/pid/smaps and /proc/pid/numa_maps similar to reduce contention on
central mmap_lock.
- The 2 patch series "refactors thpsize_shmem_enabled_store() and
thpsize_shmem_enabled_show()" from Ran Xiaokai provides some cleanup
work in the THP code.
- The 2 patch series "selftests/memfd: fix compilation warnings" from
Konstantin Khorenko fixes a few build glitches in the memfd selftest
code.
- The 4 patch series "memcg: shrink obj_stock_pcp and cache multiple
objcgs" from Shakeel Butt resolves a 68% performance regression caused
by NUMA-node cache thrashing around struct obj_stock_pcp by shrinking
its existing fields and expanding it into a multi-slot array that caches
up to five obj_cgroup pointers per CPU, allowing per-node variants of
the same memcg to coexist within a single 64-byte cache line.
- The 2 patch series "zram: writeback fixes" from Sergey Senozhatsky
addresses a couple of unrelated zram writeback issues.
- The 9 patch series "mm: switch THP shrinker to list_lru" from Johannes
Weiner resolves NUMA-awareness issues and streamlines callsite
interaction by refactoring and extending the list_lru API to completely
replace the complex, open-coded deferred split queue for Transparent
Huge Pages (THPs).
- The 2 patch series "mm: improve large folio readahead for exec memory"
from Usama Arif improves large-folio readahead on systems like 64K-page
arm64 by preventing the mmap_miss check from permanently disabling
target-oriented VM_EXEC readahead, and by generalizing the
force_thp_readahead gate to support mappings with any usefully large
maximum folio order under the cache cap.
- The 6 patch series "userfaultfd/pagemap: pre-existing fixes" from
Kiryl Shutsemau fixes a bunch of minor issues in the
userfaultfd/pagemap, all of which were flagged by Sashiko review of
proposed new material.
- The 5 patch series "mm/sparse-vmemmap: Provide generic
vmemmap_set_pmd() and vmemmap_check_pmd()" from Muchun Song provides
generic versions of these two functions so the four arch-specific
implementations can be removed.
- The 2 patch series "mm/swap, PM: hibernate: fix swapoff race in
uswsusp by pinning swap device" from Youngjun Park addresses a
uswsusp-vs-swapoff race and reduces the swap device reference
taking/releasing frequency.
- The 2 patch series "mm/hmm: A fix and a selftest" from Dev Jain does
as claimed.

treewide: fix transposed "sign" typos and update spelling.txt
Several comments transpose the letters in "assigned" and "unsigned", spelling them with "sing" instead of "sign". Correct all of them. Of these, the misspelling of "assigned" is not yet flagged by checkpatch, so also add it to scripts/spelling.txt. The remaining matches of `grep -ri singed` are RISINGEDGE register and enum names, not typos.

soc: drivers for 7.2
There are a few added drivers, but mostly the normal maintenance to drivers
for firmware, memory controller and other soc specific hadware:
- The NXP QuickEngine gets modern MSI support, which allows some cleanups to
the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC implementations,
and flexiblity around power managedment for the serial-engine driver
as well as probing the LLCC driver using custom hardware descriptions
inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed, tegra,
broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces,
to update driver probing, object lifetimes and address minor bugs.

workqueue: Changes for v7.2
- Continued progress toward making alloc_workqueue() unbound by default:
more callers converted to WQ_PERCPU / system_percpu_wq / system_dfl_wq,
and new warnings for queues that use neither WQ_PERCPU nor WQ_UNBOUND
or the legacy system_wq / system_unbound_wq.
- Misc: drop the now-trivial apply_wqattrs_lock()/unlock() wrappers,
forbid the TEST_WORKQUEUE benchmark from being built-in, and fix a
spurious pointer level in the worker debug-dump path.

Driver core changes for 7.2-rc1
- deferred probe:
- Fix race where deferred probe timeout work could be permanently
canceled by using mod_delayed_work()
- Fix missing jiffies conversion in deferred_probe_extend_timeout()
- Guard timeout extension with delayed_work_pending() to prevent
premature firing
- Use system_percpu_wq instead of the deprecated system_wq
- Update deferred_probe_timeout documentation
- device:
- Replace direct struct device bitfield access (can_match, dma_iommu,
dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
of_node_reused, offline, offline_disabled) with flag-based
accessors using bit operations
- Reject devices with unregistered buses
- Delete unused DEVICE_ATTR_PREALLOC()
- Add low-level device attribute macros with const show/store
callbacks, allowing device attributes to reside in read-only memory
- Move core device attributes to read-only memory
- Constify group array pointers in driver_add_groups() /
driver_remove_groups(), struct bus_type, and struct device_driver
- device property:
- Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id()
- Initialize all fields of fwnode_handle in fwnode_init()
- Provide swnode_get()/swnode_put() wrappers around kobject_get/put()
- Allow passing struct software_node_ref_args pointers directly to
PROPERTY_ENTRY_REF()
- driver_override:
- Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override
infrastructure, fixing a UAF from unsynchronized access to
driver_override in bus match() callbacks
- Remove the now-unused driver_set_override()
- firmware loader:
- Fix recursive lock deadlock in device_cache_fw_images() when async
work falls back to synchronous execution
- Fix device reference leak in firmware_upload_register()
- platform:
- Pass KBUILD_MODNAME through the platform driver registration macro
to create module symlinks in sysfs for built-in drivers; move
module_kset initialization to a pure_initcall and tegra cbb
registration to core_initcall to ensure correct ordering
- Pass THIS_MODULE implicitly through a coresight_init_driver() macro
- sysfs:
- Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
WARN
- Add return value clamping to sysfs_kf_read()
- Rust:
- ACPI:
- Fix missing match data for PRP0001 by exporting
acpi_of_match_device()
- Auxiliary:
- Replace drvdata() with dedicated registration data on
auxiliary_device. drvdata() exposed the driver's bus device
private data beyond the driver's own scope, creating ordering
constraints and forcing the data to outlive all registrations
that access it. Registration data is instead scoped structurally
to the Registration object, making lifecycle ordering enforced
by construction rather than convention.
- Rust-native device driver lifetimes (HRT):
- Allow Rust device drivers to carry a lifetime parameter on their
bus device private data, tied to the device binding scope -- the
interval during which a bus device is bound to a driver. Device
resources like pci::Bar<'a> and IoMem<'a> can be stored directly
in the driver's bus device private data with a lifetime bounded
by the binding scope, so the compiler enforces at build time that
they do not outlive the binding. This removes Devres indirection
from every access site and eliminates try_access() failure paths
in destructors.
Bus driver traits use a Generic Associated Type (GAT)
Data<'bound> to introduce the lifetime on the private data,
rather than parameterizing the Driver trait itself. Auxiliary
registration data, where the lifetime is not introduced by a
trait callback but must be threaded through Registration, uses
the ForLt trait (a type-level abstraction for types generic over
a lifetime).
- Misc:
- Fix DT overlayed devices not probing by reverting the broken
treewide overlay fix and re-running fw_devlink consumer pickup when
an overlay is applied to a bound device
- Use root_device_register() for faux bus root device; add sanity
check for failed bus init
- Fix dev_has_sync_state() data race with READ_ONCE() and move it to
base.h
- Avoid spurious device_links warning when removing a device while
its supplier is unbinding
- Switch ISA bus to dynamic root device
- Fix suspicious RCU usage in kernfs_put()
- Remove devcoredump exit callback
- Constify devfreq_event_class

drm/xe: fix job timeout recovery for unstarted jobs and kernel queues
A job that GuC never scheduled (never started) indicates a GuC
scheduling failure; previously such jobs were silently errored out
instead of triggering a GT reset to recover. Trigger a GT reset and
resubmit them, but only when the queue was not already killed or banned:
an unstarted job on an already banned queue is the ban working as
intended and must neither clear the ban nor kick off a reset, otherwise
a banned userspace queue could be resurrected and spam GT resets.
Kernel queues are always recovered this way and wedge the device once
recovery attempts are exhausted, since kernel work must not silently
fail. A started job that times out on a userspace VM bind queue stays
banned rather than being reset and retried.
The queue is banned early in the timeout handler to signal the G2H
scheduling-done handler so it wakes the disable-scheduling waiter;
without it the waiter sleeps the full 5s timeout. When a reset is
warranted the ban is cleared before rearming so that
guc_exec_queue_start() can resubmit jobs after the GT reset - a
still-banned queue would block resubmission and cause an infinite TDR
loop. The already-banned case is gated out before this point via
skip_timeout_check, so it is unaffected.
v2: (Himal) Do it for any queue type, not just kernel/migration
v3: - (Sashiko and Sanjay): don't clear the ban / GT reset for already
killed/banned queues on unstarted-job timeout
- Update commit message
- (Matt) Add Fixes tag

drm/xe: fix refcount leak in xe_range_fence_insert()
xe_range_fence_insert() acquires a reference on fence via dma_fence_get() and stores it in rfence->fence. It then calls dma_fence_add_callback() and handles two cases: when the callback is successfully registered (err == 0) the fence is transferred to the tree for later cleanup; when the fence is already signaled (err == -ENOENT) it manually drops the extra reference with dma_fence_put(fence). However, dma_fence_add_callback() can fail with other errors (e.g. -EINVAL) and in that case the code falls through to the free: label without releasing the acquired reference, leaking it. Fix the leak by adding an else branch that calls dma_fence_put() before jumping to free: for any error other than -ENOENT. Fixes: |

drm/xe: include all registered queues in TLB invalidation
Context-based TLB invalidation currently selects only scheduling-active
exec queues via q->ops->active(). During rebind flows, queues may be
suspended (or transitioning through resume) while still owning valid
translations, causing them to be skipped from invalidation and leading
to missed TLB invalidations on LR rebinds.
The underlying issue is a TOCTOU: q->guc->state bits are flipped lock-free
from enable_scheduling(), disable_scheduling{,_deregister}(), the
suspend/resume sched-msg handlers, handle_sched_done(), and
guc_exec_queue_stop(); nothing in send_tlb_inval_ctx_ppgtt() serializes
against them, so any state-based predicate can race.
Include all the registered queues so that TLB invalidations are not
missed. This is race-free because list membership on vm->exec_queues.list
is stable under vm->exec_queues.lock held by the caller. The performance
impact is expected to be minimal and harmless. If it does turn out to be
a concern, we can come back with a race-safe solution to ignore certain
queues.

drm/xe/display: fix oops in suspend/shutdown without display
The xe driver keeps track of whether to probe display, and whether display hardware is there, using xe->info.probe_display. It gets set to false if there's no display after intel_display_device_probe(). However, the display may also be disabled via fuses, detected at a later time in intel_display_device_info_runtime_init(). In this case, the xe driver does for_each_intel_crtc() on uninitialized mode config in xe_display_flush_cleanup_work(), leading to a NULL pointer dereference, and generally calls display code with display info cleared. Check for intel_display_device_present() after intel_display_device_info_runtime_init(), and reset xe->info.probe_display as necessary. Also do unset_display_features() for completeness, although display runtime init has already done that. This will need to be unified across all cases later. Move intel_display_device_info_runtime_init() call slightly earlier, similar to i915, to avoid a bunch of unnecessary setup for no display cases. Note #1: The xe driver has no business doing low level display plumbing like for_each_intel_crtc() to begin with. It all needs to happen in display code. Note #2: The actual bug is present already in commit |

drm/amd/display: use plane color_mgmt_changed to track colorop changes
Ensure the driver tracks changes in any colorop property of a plane
color pipeline by using the same mechanism of CRTC color management and
update plane color blocks when any colorop property changes. It fixes an

shaper/3D-LUT updates.

drm/atomic: track individual colorop updates
As we do for CRTC color mgmt properties, use color_mgmt_changed flag to track any value changes in the color pipeline of a given plane, so that drivers can update color blocks as soon as plane color pipeline or individual colorop values change. Since we're here, only announce and track changes to plane COLOR_PIPELINE prop if its value is actually changing. Fixes: |

drm/vc4: fix krealloc() memory leak
Don't just overwrite the original pointer passed to krealloc()
with its return value without checking latter:
MEM = krealloc(MEM, SZ, GFP);
If krealloc() returns NULL, that erases the pointer
to the still allocated memory, hence leaks this memory.
Instead, use a temporary variable, check it's not NULL
and only then assign it to the original pointer:
TMP = krealloc(MEM, SZ, GFP);
if (!TMP) return;
MEM = TMP;
While on it, use krealloc_array().

drm/i915/edp: Check supported link rates DPCD read
intel_edp_set_sink_rates() reads DP_SUPPORTED_LINK_RATES into a local stack array and then parses the array unconditionally. If the read fails, the array contents are not valid and may result in bogus sink link rates being used. Use drm_dp_dpcd_read_data() and clear the sink rate array on failure, so the existing parser falls back to the default sink rate handling.

drm/virtio: fix dma_fence refcount leak on error in virtio_gpu_dma_fence_wait()
dma_fence_unwrap_for_each() internally calls dma_fence_unwrap_first()
which does cursor->chain = dma_fence_get(head), taking an extra
reference. On normal loop completion, dma_fence_unwrap_next()
releases this via dma_fence_chain_walk() -> dma_fence_put().
When virtio_gpu_do_fence_wait() fails and the function returns early
from inside the loop, the cursor->chain reference is never released.
This is the only caller in the entire kernel that does an early return
inside dma_fence_unwrap_for_each.
Add dma_fence_put(itr.chain) before the early return.

DRM Rust changes for v7.2-rc1
- Driver Core (shared via signed tag dd-lifetimes-7.2-rc1):
- Introduce Higher-Ranked Lifetime Types (HRT) for Rust device
drivers, allowing driver structs to hold device resources like
pci::Bar and IoMem directly with a lifetime tied to the binding
scope, removing the need for Devres indirection and ARef<Device>.
- Replace drvdata() with scoped registration data on the auxiliary
bus, using the new ForLt trait to thread lifetimes through
registrations. Remove drvdata() and driver_type.
- DRM:
- Add GPUVM immediate mode abstraction for Rust GPU drivers:
- In immediate mode, GPU virtual address space state is updated
during job execution (in the DMA fence signalling critical path),
keeping the GPUVM and the GPU's address space always in sync.
- Provide GpuVm, GpuVa, and GpuVmBo types for managing address
spaces, virtual mappings, and GEM object backing respectively.
- Provide split-merge map/unmap operations that handle partial
overlaps with existing mappings.
- drm_exec integration for dma_resv locking and GEM object
validation based on the external/evicted object lists are not
yet covered and planned as follow-up work.
- Introduce DeviceContext type state for drm::Device, allowing
drivers to restrict operations to contexts where the device is
guaranteed to be registered (or not yet registered) with userspace.
- Add FEAT_RENDER flag to the Driver trait for render node support.
- Nova:
- Hopper/Blackwell enablement:
- Add GPU identification and architecture-based HAL selection for
Hopper (GH100) and Blackwell (GB100, GB202).
- Implement the FSP (Foundation Security Processor) boot path used by
Hopper and Blackwell, including FSP falcon engine support, EMEM
operations, MCTP/NVDM message infrastructure, and FSP Chain of
Trust boot with GSP lockdown release.
- Add support for 32-bit firmware images and auto-detection of
firmware image format.
- Add architecture-specific framebuffer, sysmem flush, PCI config
mirror, DMA mask, and WPR/non-WPR heap sizing.
- GSP boot and unload:
- Refactor the GSP boot process into a chipset-specific HAL,
keeping the SEC2 and FSP boot paths separated cleanly.
- Implement proper driver unload: send UNLOADING_GUEST_DRIVER
command, run Booter Unloader and FWSEC-SB upon unbinding, and run
the unload bundle on Gsp::boot() failure. This removes the need
for a manual GPU reset between driver unbind and re-probe.
- GA100 support:
- Add support for the GA100 GPU, including IFR header detection and
skipping, correct fwsignature selection, conditional FRTS boot,
and documentation of the IFR header layout.
- VBIOS hardening and refactoring:
- Harden VBIOS parsing with checked arithmetic, bounds-checked
accesses, and FromBytes-based structure reads throughout the FWSEC
and Falcon data paths. Simplify the overall VBIOS module
structure.
- HRT adoption:
- Use lifetime-parameterized pci::Bar directly, replacing the
Arc<Devres<Bar0>> indirection. Replace ARef<Device> with &'bound
Device in SysmemFlush and the GSP sequencer. Separate the driver
type from driver data.
- Misc:
- Rename module names to kebab-case (nova-drm, nova-core).
- Require little-endian in Kconfig, making the existing assumption
explicit.
- Tyr:
- Define comprehensive typed register blocks for GPU_CONTROL,
JOB_CONTROL, MMU_CONTROL (including per-address-space registers),
and DOORBELL_BLOCK using the kernel register!() macro. This replaces
manual bit manipulation with typed register and field accessors.
- Add shmem-backed GEM objects and set DMA mask based on GPU physical
address width.
- Adopt HRT: separate driver type from driver data, and use IoMem
directly instead of Devres for register access during probe.
- Move clock cleanup into a Drop implementation.

drm/amdkfd: Unwind debug trap enable on copy_to_user failure
If kfd_dbg_trap_enable() fails while copying runtime_info to userspace,
it had already activated the trap, set debug_trap_enabled, taken an extra
process reference, and opened the debug event file. Return -EFAULT without
unwinding that state, leaving inconsistent trap state and a refcount
imbalance that could break later DISABLE/ENABLE.
On copy_to_user failure, deactivate the trap and undo the rest of the
enable setup before returning.

drm/amdkfd: Add bounds check for AMDKFD_IOC_WAIT_EVENTS
The kfd_wait_on_events ioctl passes a user-supplied num_events parameter
directly to alloc_event_waiters() which calls kcalloc() without validation.
This allows unprivileged users with /dev/kfd access to trigger large kernel
memory allocations, potentially causing memory exhaustion and denial of
service via the OOM killer.
Add a check to reject num_events values exceeding KFD_SIGNAL_EVENT_LIMIT
(4096), which is the maximum number of events a single process can create.

drm/amdkfd: fix SMI event cross-process information leak
kfd_smi_ev_enabled() skips the suser privilege check when pid=0.
PROCESS_START, PROCESS_END, and VMFAULT events are emitted with
pid=0 while carrying another process's PID and command name, so any
/dev/kfd user in the render group can monitor all GPU workloads.
Pass the target process PID into kfd_smi_event_add() for these events
so the existing per-client filter restricts delivery to the owning
process or CAP_SYS_ADMIN subscribers.
