Move the call to preempt_prepare_postamble() after verifying that
preempt_postamble_ptr is valid. If preempt_postamble_ptr is NULL,
dereferencing it in preempt_prepare_postamble() would lead to a crash.
This change avoids calling the preparation function when the

this series fixes the error regarding duplicate debugfs directory creation on
TQMa8MPxL (imx8mp) when easrc is enabled:
debugfs: '30c90000.easrc' already exists in 'tqm-tlv320aic32'
This is caused because fsl_easrc adds two components which use the device name
as component name. Debugfs directories for each component is created, resulting
on name conflict. Fix this by adding the debugfs_prefix for both component
drivers.
Before:
$ ls /sys/kernel/debug/asoc/tqm-tlv320aic32/
30c30000.sai 30c90000.easrc HiFi-ASRC-FE dapm dapm_pop_time
dma:30c30000.sai tlv320aic32x4.1-0018
After:
$ ls /sys/kernel/debug/asoc/tqm-tlv320aic32/
30c30000.sai HiFi-ASRC-FE asrc:30c90000.easrc dapm dapm_pop_time
dma:30c30000.sai easrc:30c90000.easrc tlv320aic32x4.1-0018
On 32‑bit systems, phys_addr_t is defined as u32. However, parisc
expects physical addresses to be 64‑bit values so it can store a
validity bit in the upper byte.
Resolve this mismatch by casting the physical address to unsigned
long, ensuring it is treated as a 64‑bit value where required. This
fixes the failure to start block device drivers on the C3700
platform, as reported by Guenter.
QEMU command line to reproduce the issue (with Debian SID as rootfs):
qemu-system-hppa -machine C3700 \
-kernel arch/parisc/boot/bzImage \
-append "console=ttyS0 \
root=/dev/sda rw rootwait panic=-1" \
-nographic \
-device lsi53c895a \
-drive file=rootfs-hppa.img,if=none,format=raw,id=hd0 \

The function save_v_state() served two purposes. First, it saved
extension context into the signal stack. Then, it constructed the
extension header if there was no fault. The second part is independent
of the extension itself. As a result, we can pull that part out, so
future extensions may reuse it. This patch adds arch_ext_list and makes
setup_sigcontext() go through all possible extensions' save() callback.
The callback returns a positive value indicating the size of the
successfully saved extension. Then the kernel proceeds to construct the
header for that extension. The kernel skips an extension if it does
not exist, or if the saving fails for some reasons. The error code is
propagated out on the later case.
This patch does not introduce any functional changes.

- Add Documentation/core-api/tracepoint.rst to TRACING in MAINTAINERS file
Updates to the tracepoint.rst document should be reviewed by the
tracing maintainers.
- Fix warning triggered by perf attaching to synthetic events
The synthetic events do not add a function to be registered when
perf attaches to them. This causes a warning when perf registers
a synthetic event and passes a NULL pointer to the tracepoint register
function. Ideally synthetic events should be updated to work with
perf, but as that's a feature and not a bug fix, simply now return
-ENODEV when perf tries to register an event that has a NULL pointer
for its function. This no longer causes a kernel warning and simply
causes the perf code to fail with an error message.

Merge tag 'fsnotify_for_v6.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull fsnotify fixes from Jan Kara:
"Two fsnotify fixes.
The fix from Ahelenia makes sure we generate event when modifying
inode flags, the fix from Amir disables sending of events from device
inodes to their parent directory as it could concievably create a
usable side channel attack in case of some devices and so far we
aren't aware of anybody depending on the functionality"
* tag 'fsnotify_for_v6.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
fs: send fsnotify_xattr()/IN_ATTRIB from vfs_fileattr_set()/chattr(1)
fsnotify: do not generate ACCESS/MODIFY events on child for special files
Merge power capping fixes for 6.19-rc2:
- Fix CPU hotplug locking deadlock reported by lockdep after a recent
update of the Intel RAPL power capping driver (Srinivas Pandruvada)
- Fix sscanf() error return value handling in the power capping core
and a race condition in register_control_type() (Sumeet Pawnikar)
* pm-powercap:
powercap: intel_rapl: Fix possible recursive lock warning
powercap: fix sscanf() error return value handling
powercap: fix race condition in register_control_type()
SX controls are currently broken, since the clamp introduced in
commit a0ce874cfa ("ASoC: ops: improve snd_soc_get_volsw") does not
handle SX controls, for example where the min value in the clamp is
greater than the max value in the clamp.
Add clamp parameter to prevent clamping in SX controls.
The nature of SX controls mean that it wraps around 0, with a variable
number of bits, therefore clamping the value becomes complicated and
prone to error.
Fixes 35 kunit tests for soc_ops_test_access.
