When we exec a new task we forget to flush the set of locked GCS mode bits.
Since we do flush the rest of the state this means that if GCS is locked
the new task will be unable to enable GCS, it will be locked as being
disabled. Add the expected flush.

Since commit 7137a203b251 ("arm64/fpsimd: Permit kernel mode NEON with
IRQs off"), the only condition under which the fallback path is taken
for FP/SIMD preserve/restore across a EFI runtime call is when it is
called from hardirq or NMI context.
In practice, this only happens when the EFI pstore driver is called to
dump the kernel log buffer into a EFI variable under a panic, oops or
emergency_restart() condition, and none of these can be expected to
result in a return to user space for the task in question.
This means that the existing EFI-specific logic for preserving and
restoring SVE/SME state is pointless, and can be removed.
Instead, kill the task, so that an exceedingly unlikely inadvertent
return to user space does not proceed with a corrupted FP/SIMD state.
Also, retain the preserve and restore of the base FP/SIMD state, as that
might belong to kernel mode use of FP/SIMD. (Note that EFI runtime calls
are never invoked reentrantly, even in this case, and so any interrupted
kernel mode FP/SIMD usage will be unrelated to EFI)

TL;DR: checking force_pte_mapping() in arch_kfence_init_pool() is
sufficient
Commit ce2b3a50ad92 ("arm64: mm: Don't sleep in
split_kernel_leaf_mapping() when in atomic context") recently added
an arm64 implementation of arch_kfence_init_pool() to ensure that
the KFENCE pool is PTE-mapped. Assuming that the pool was not
initialised early, block splitting is necessary if the linear
mapping is not fully PTE-mapped, in other words if
force_pte_mapping() is false.
arch_kfence_init_pool() currently makes another check: whether
BBML2-noabort is supported, i.e. whether we are *able* to split
block mappings. This check is however unnecessary, because
force_pte_mapping() is always true if KFENCE is enabled and
BBML2-noabort is not supported. This must be the case by design,
since KFENCE requires PTE-mapped pages in all cases. We can
therefore remove that check.
The situation is different in split_kernel_leaf_mapping(), as that
function is called unconditionally regardless of the configuration.
If BBML2-noabort is not supported, it cannot do anything and bails
out. If force_pte_mapping() is true, there is nothing to do and it
also bails out, but these are independent checks.
Commit 53357f14f924 ("arm64: mm: Tidy up force_pte_mapping()")
grouped these checks into a helper, split_leaf_mapping_possible().
This isn't so helpful as only split_kernel_leaf_mapping() should
check both. Revert the parts of that commit that introduced the
helper, reintroducing the more accurate comments in
split_kernel_leaf_mapping().

Fix inconsistent error handling for sscanf() return value check.
Implicit boolean conversion is used instead of explicit return
value checks. The code checks if (!sscanf(...)) which is incorrect
because:
1. sscanf returns the number of successfully parsed items
2. On success, it returns 1 (one item passed)
3. On failure, it returns 0 or EOF
4. The check 'if (!sscanf(...))' is wrong because it treats
success (1) as failure
All occurrences of sscanf() now uses explicit return value check.
With this behavior it returns '-EINVAL' when parsing fails (returns
0 or EOF), and continues when parsing succeeds (returns 1).

or another thread tries to register a zone immediately after
device_register(), the control_type_valid() will fail because
the control_type is not yet in the list. The IDR is not yet
initialized, so this race condition causes zone registration
failure.

Rockchip RK3576 EVB1 has an onboard PCIe slot (PCIe 2.1, x4 mechanically,
x1 electrically), but it shares pins and PHY with the only USB3 Type-A
port.
There is a physical switch next to the slot to transfer respective pins
connection from the USB3 port to the PCIe slot, but apart from flipping
the switch one must also disable the USB3 host controller to prevent it
from claiming the PHY before the PCIe slot can become usable.
Add an overlay to disable the USB3 host port and instead enable the
PCIe slot, along with its pin configs. The physical switch must still be
flipped to the "ON - PCIe1" position for this to work.

Till now, the runtime PM workqueue has been flagged as freezable, so it
does not process work items during system-wide PM transitions like
system suspend and resume. The original reason to do that was to
reduce the likelihood of runtime PM getting in the way of system-wide
PM processing, but now it is mostly an optimization because (1) runtime
suspend of devices is prevented by bumping up their runtime PM usage
counters in device_prepare() and (2) device drivers are expected to
disable runtime PM for the devices handled by them before they embark
on system-wide PM activities that may change the state of the hardware
or otherwise interfere with runtime PM. However, it prevents
asynchronous runtime resume of devices from working during system-wide
PM transitions, which is confusing because synchronous runtime resume
is not prevented at the same time, and it also sometimes turns out to
be problematic.
For example, it has been reported that blk_queue_enter() may deadlock
during a system suspend transition because of the pm_request_resume()
usage in it [1]. It may also deadlock during a system resume transition
in a similar way. That happens because the asynchronous runtime resume
of the given device is not processed due to the freezing of the runtime
PM workqueue. While it may be better to address this particular issue
in the block layer, the very presence of it means that similar problems
may be expected to occur elsewhere.
For this reason, remove the WQ_FREEZABLE flag from the runtime PM
workqueue and make device_suspend_late() use the generic variant of
pm_runtime_disable() that will carry out runtime PM of the device
synchronously if there is pending resume work for it.
Also update the comment before the pm_runtime_disable() call in
device_suspend_late(), to document the fact that the runtime PM
should not be expected to work for the device until the end of
device_resume_early(), and update the related documentation.
This change may, even though it is not expected to, uncover some
latent issues related to queuing up asynchronous runtime resume
work items during system suspend or hibernation. However, they
should be limited to the interference between runtime resume and
system-wide PM callbacks in the cases when device drivers start
to handle system-wide PM before disabling runtime PM as described
above.

Enable CLK_SET_RATE_PARENT for mux clocks so that rate changes can properly
propagate to their parent clocks. Several clocks in the R9A09G077 CPG tree
depend on upstream PLL or divider outputs being recalculated when a child
requests a new frequency. Without this flag, rate adjustments stop at the
mux layer, leaving parent rates unchanged and preventing the clock tree
from converging on the intended values.
Set the flag in DEF_MUX to ensure that parent clocks participate in rate
negotiation, which is required for correct operation of the display and
peripheral related clocks being added for RZ/T2H support.

Define the new SCKCR fields FSELXSPI0/FSELXSPI1 and DIVSEL_XSPI0/1 and
add two new core clocks XSPI_CLK0 and XSPI_CLK1. The xSPI block uses
PCLKH as its bus clock (use as module clock parent) while the operation
clock (XSPI_CLKn) is derived from PLL4. To support this arrangement
provide mux/div selectors and divider tables for the supported
XSPI operating rates.
Add CLK_TYPE_RZT2H_FSELXSPI to implement a custom divider/mux clock

when the parent output is 600MHz only dividers 8 and 16 are valid,
whereas for 800MHz operation the full divider set (6,8,16,32,64) may
be used. The custom determine_rate() picks the best parent/divider pair
to match the requested rate and programs the appropriate SCKCR fields.

Although CMN-Skeena is mildly modified for the Morello hardware
architecture, it still identifies itself as CMN-600 r3p1. Since
there are also no documented changes to its PMU functionality,
we can make the PMU accessible via the standard CMN-600 binding.
In general, PMU registers are non-functional on CMN Fast Models,
so this is only meaningful for the real SDP hardware.

The FF-A driver currently performs loose comparisons when checking the
supported FF-A feature, which can inadvertently treat future or
intermediate revisions as compatible.
Replace generic `version {>,<} FFA_VERSION_1_*` pattern checks with
feature-specific macros that clearly express which functionality
depends on FF-A versioning.
This improves readability and future maintainability by tying each
feature (e.g. GET_COUNT_ONLY, size/UUID/exec state in responses) to
explicit version requirements instead of relying on generic version
comparisons. This improves robustness and clarity as the FF-A
specification evolves.
No functional change, only improves code readability.

Commit 9ac09bb9feac ("mm: consistently use current->mm in
mm_get_unmapped_area()") upstream dropped a parameter from
mm_get_unmapped_area() while commit 99bda20d6d4c ("drm/gem: Introduce
drm_gem_get_unmapped_area() fop") in drm-misc-next added a new user.
Drop the extra parameter from the call.

The XFRM_STATE_NOPMTUDISC flag is only meaningful for output SAs, but
it was being applied regardless of the SA direction when the sysctl
ip_no_pmtu_disc is enabled. This can unintentionally affect input SAs.
Limit setting XFRM_STATE_NOPMTUDISC to output SAs when the SA direction
is configured.

The video clocks enci, encp, vdac and hdmitx share the same clock
source. Adding CLK_SET_RATE_PARENT to the mux may unintentionally change
the shared parent clock, which could affect other video clocks.

Currently it seems impossible to observe these changes to the file's
attributes. It's useful to be able to do this to see when the file
becomes immutable, for example, so emit IN_ATTRIB via fsnotify_xattr(),
like when changing other inode attributes.

inotify/fanotify do not allow users with no read access to a file to
subscribe to events (e.g. IN_ACCESS/IN_MODIFY), but they do allow the
same user to subscribe for watching events on children when the user
has access to the parent directory (e.g. /dev).
Users with no read access to a file but with read access to its parent
directory can still stat the file and see if it was accessed/modified
via atime/mtime change.
The same is not true for special files (e.g. /dev/null). Users will not
generally observe atime/mtime changes when other users read/write to
special files, only when someone sets atime/mtime via utimensat().
Align fsnotify events with this stat behavior and do not generate
ACCESS/MODIFY events to parent watchers on read/write of special files.
The events are still generated to parent watchers on utimensat(). This
closes some side-channels that could be possibly used for information
exfiltration [1].

When pdacf_config() fails, snd_pdacf_probe() returns the error code
directly without freeing the sound card resources allocated by
snd_card_new(), which leads to a memory leak.
Add proper error handling to free the sound card and clear the card
list entry when pdacf_config() fails.
