drm/xe/guc: Exclude indirect ring state page from ADS engine state size
The engine state size reported to GuC via ADS should only include the
engine state portion and should not include the indirect ring state page
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
want it to overwrite the indirect ring state as well.

drm/xe/pf: Fix MMIO access using PF view instead of VF view during migration
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().

drm/xe/pf: Fix EAGAIN sign in pf_migration_consume()
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().

drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()
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.

Pull cgroup fixes from Tejun Heo:
- During v6.19, cgroup task unlink was moved from do_exit() to after the
final task switch to satisfy a controller invariant. That left the kernel
seeing tasks past exit_signals() longer than userspace expected, and
several v7.0 follow-ups tried to bridge the gap by making rmdir wait for
the kernel side. None held up.
The latest is an A-A deadlock when rmdir is invoked by the reaper of
zombies whose pidns teardown the rmdir itself is waiting on, which
points at the synchronizing approach being fundamentally wrong.
Take a different approach: drop the wait, leave rmdir's user-visible
side returning as soon as cgroup.procs is empty, and defer the css
percpu_ref kill that drives ->css_offline() until the cgroup is fully
depopulated.
Tagged for stable. Somewhat invasive but contained. The hope is that
fixing forward sticks. If not, the fallback is to revert the entire
chain and rework on the development branch.
Note that this doesn't plug a pre-existing analogous race in
cgroup_apply_control_disable() (controller disable via
subtree_control). Not a regression. The development branch will do
the more invasive restructuring needed for that.

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

overwrite the engine state in the LRC on watchdog resets and we don't

ffa_sched_recv_cb_update() used list_for_each_entry_safe() to search for

with an invalid pointer. Use a normal iterator and detect the not-found
case correctly before touching the partition state.
firmware: arm_ffa: Snapshot notifier callbacks under lock
Both notification handlers currently look up a notifier callback under
notify_lock, drop the lock, and then dereference the returned
notifier entry. A concurrent unregister can delete and free that
entry in the gap, leaving the handler to dereference stale memory.
Copy the callback pointer and callback data while notify_lock is
still held and invoke the callback only after the lock is dropped.
This keeps the existing callback execution model while removing the
use-after-free window in both the framework and non-framework
notification paths.
firmware: arm_ffa: Align RxTx buffer size before mapping
Commit 83210251fd70 ("firmware: arm_ffa: Use the correct buffer size during
RXTX_MAP") advertises PAGE_ALIGN(rxtx_bufsz) to firmware when mapping the
buffers but the driver continues to stores the minimum FF-A buffer size
in drv_info->rxtx_bufsz which is used elsewhere in the driver.
Align the size before storing it so that the allocation, validation and
FFA_RXTX_MAP all use the same buffer size.
Framework notifications carry an indirect message in the shared RX
buffer. Validate the reported offset and size before using them, reject
zero-length payloads, and ensure that any non-header payload starts at
the UUID field rather than in the middle of the message header.
Use the validated offset and size values for both kmemdup() and the UUID
parsing path so malformed firmware data cannot drive an out-of-bounds
read or an oversized allocation.
firmware: arm_ffa: Keep framework RX release under lock
The framework notification handler drops rx_lock before issuing
FFA_RX_RELEASE, leaving a window where another RX-buffer user can
start a new FF-A transaction before ownership has actually been
returned to firmware.
Move the FFA_RX_RELEASE calls so they execute while rx_lock is still
held on both the kmemdup() failure path and the normal success path.
While doing that, switch the handler to scoped_guard() to keep the
critical section explicit.
The register-based PARTITION_INFO_GET path trusted the firmware-provided
indices when copying partition descriptors into the caller buffer.
Reject inconsistent counts or index progressions so the copy loop cannot
write past the allocated array.
Extend the guidelines when to use fallback compatibles to cover to
common review responses. Devices are most likely compatible and should
use fallbacks when having:
1. Compatible programming interface, meaning one is a subset, and Linux
device drivers can use the subset to correctly match/bind and still
operate with the subset features.
2. Device variant discovery through some means, like registers.
Devices are incompatible and fallback is not suitable when that
fallback cannot be used by the drivers to match/bind. In the same time
commit message should clearly explain when the code suggests devices
are compatible, but the binding does not define them as such.
of/fdt: remove redundant memset in __unflatten_device_tree()
Now that memblock and slab allocators are the only allocators and both
return zero-initialized memory, zeroing the memory ourselves is
redundant. The allocators used are:
- kernel_tree_alloc uses kzalloc()
- early_init_dt_alloc_memory_arch() and dt_alloc_memory() both use
memblock_alloc()
Remove redundant memset after the allocation. No funtional change.
The 'wakeup-source' property already has its type defined in the core
schema. Remove the redundant 'type: boolean' from the binding file to
