The newly added integrity_recheck() function has another larger stack
allocation, just like its caller integrity_metadata(). When it gets
inlined, the combination of the two exceeds the warning limit for 32-bit
architectures and possibly risks an overflow when this is called from
a deep call chain through a file system:
drivers/md/dm-integrity.c:1767:13: error: stack frame size (1048) exceeds limit (1024) in 'integrity_metadata' [-Werror,-Wframe-larger-than]
1767 | static void integrity_metadata(struct work_struct *w)
Since the caller at this point is done using its checksum buffer,
just reuse the same buffer in the new function to avoid the double
allocation.
[Mikulas: add "noinline" to integrity_recheck and verity_recheck.
These functions are only called on error, so they shouldn't bloat the
stack frame or code size of the caller.]

Commit 47f419e07111 ("drm/dp: move intel_dp_vsc_sdp_pack() to generic helper")
and commit b55b88d86fec ("drm/dp: drop the size parameter from drm_dp_vsc_sdp_pack()")
were based on top of a tree containing the
commit 31a5b6ed88c7 ("drm/i915/display: Unify VSC SPD preparation") but
landed in a tree where this commit didn't exist, leaving behind a spurious
case calling for a removed function: intel_dp_vsc_sdp_pack()
Let's convert the remaining case here so we can port this patch to
any tree that doesn't contain
commit 31a5b6ed88c7 ("drm/i915/display: Unify VSC SPD preparation")
In in kind of merge where this commit does exist, this line here will

Currently, the V3D driver uses PAGE_SHIFT over the assumption that
PAGE_SHIFT = 12, as the PAGE_SIZE = 4KB. But, the RPi 5 is using
PAGE_SIZE = 16KB, so the MMU PAGE_SHIFT is different than the system's
PAGE_SHIFT.
Enable V3D to be used in system's with any PAGE_SIZE by making sure that
everything MMU-related uses the MMU page shift.

Pull ata fixes from Niklas Cassel:
- Do not try to set a sleeping device to standby. Sleep is a deeper
sleep state than standby, and needs a reset to wake up the drive. A
system resume will reset the port. Sending a command other than reset
to a sleeping device is not wise, as the command will timeout (Damien
Le Moal)
- Do not try to put a device to standby twice during system shutdown.
ata_dev_power_set_standby() is currently called twice during
shutdown, once after the scsi device is removed, and another when
ata_pci_shutdown_one() executes. Modify ata_dev_power_set_standby()
to do nothing if the device is already in standby (Damien Le Moal)
- Add a quirk for ASM1064 to fixup the number of implemented ports. We
probe all ports that the hardware reports to be implemented. Probing
ports that are not implemented causes significantly increased boot

Prior to commit 092edaddb660 ("iommu: Support mm PASID 1:n with sva
domains") the code allowed a SVA handle to be bound multiple times to the
same (mm, device) pair. This was alluded to in the kdoc comment, but we
had understood this to be more a remark about allowing multiple devices,
not a literal same-driver re-opening the same SVA.
It turns out uacce and idxd were both relying on the core code to handle
reference counting for same-device same-mm scenarios. As this looks hard
to resolve in the drivers bring it back to the core code.
The new design has changed the meaning of the domain->users refcount to
refer to the number of devices that are sharing that domain for the same
mm. This is part of the design to lift the SVA domain de-duplication out
of the drivers.
Return the old behavior by explicitly de-duplicating the struct iommu_sva
handle. The same (mm, device) will return the same handle pointer and the
core code will handle tracking this. The last unbind of the handle will
destroy it.

All the checks currently done in kvm_check_cpucfg can be realized with
early returns, so just do that to avoid extra cognitive burden related
to the return value handling.
While at it, clean up comments of _kvm_get_cpucfg_mask() and
kvm_check_cpucfg(), by removing comments that are merely restatement of
the code nearby, and paraphrasing the rest so they read more natural for
English speakers (that likely are not familiar with the actual Chinese-
influenced grammar).
No functional changes intended.

The function is not actually a getter of guest CPUCFG, but rather
validation of the input CPUCFG ID plus information about the supported
bit flags of that CPUCFG leaf. So rename it to avoid confusion.

The range check for the CPUCFG ID is wrong (should have been a ||
instead of &&) and useless in effect, so fix the obvious mistake.
Furthermore, the juggling of the temp return value is unnecessary,
because it is semantically equivalent and more readable to just
return at every switch case's end. This is done too to avoid potential
bugs in the future related to the unwanted complexity.
Also, the return value of _kvm_get_cpucfg is meant to be checked, but
this was not done, so bad CPUCFG IDs wrongly fall back to the default
case and 0 is incorrectly returned; check the return value to fix the
UAPI behavior.
While at it, also remove the redundant range check in kvm_check_cpucfg,
because out-of-range CPUCFG IDs are already rejected by the -EINVAL
as returned by _kvm_get_cpucfg().

The unflatten_and_copy_device_tree() function contains a call to
memblock_alloc(). This means that memblock is allocating memory before
any of the reserved memory regions are set aside in the arch_mem_init()
function which calls early_init_fdt_scan_reserved_mem(). Therefore,
there is a possibility for memblock to allocate from any of the
reserved memory regions.
Hence, move the call to early_init_fdt_scan_reserved_mem() to be earlier
in the init sequence, so that the reserved memory regions are set aside
before any allocations are done using memblock.

If fixed refresh rate program the PKGC_LATENCY register
with the highest latency from level 1 and above LP registers
and program ADDED_WAKE_TIME = DSB execution time.
else program PKGC_LATENCY with all 1's and ADDED_WAKE_TIME as 0.
This is used to improve package C residency by sending the highest
latency tolerance requirement (LTR) when the planes are done with the
frame until the next frame programming window (set context latency,
window 2) starts.

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1].
As the "q" variable is a pointer to "struct xe_exec_queue" and this
structure ends in a flexible array:
struct xe_exec_queue {
[...]
struct xe_lrc lrc[];
};
the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the argument "size + size * count" in the
kzalloc() function.
This way, the code is more readable and more safer.

Commit a0df2cc858c3 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace")
inadvertently reverted commit 8d038f49c1f3 ("drm/xe: Fix cast on trace
variable"), breaking the build on 32bits.
As noted by Ville, there's no point in converting the pointers to u64
and add casts everywhere. In fact, it's better to just use %p and let
the address be hashed. Convert all the cases in xe_trace.h to use
pointers.

MSA. Hence add an API which indicates the sink support which can be used
by the rest of the DP programming.

maintainers
