ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

Merge tag 'selinux-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

- Improve the granularity of SELinux labeling for memfd files

Currently when creating a memfd file, SELinux treats it the same as
any other tmpfs, or hugetlbfs, file. While simple, the drawback is
that it is not possible to differentiate between memfd and tmpfs
files.

This adds a call to the security_inode_init_security_anon() LSM hook
and wires up SELinux to provide a set of memfd specific access
controls, including the ability to control the execution of memfds.

As usual, the commit message has more information.

- Improve the SELinux AVC lookup performance

Adopt MurmurHash3 for the SELinux AVC hash function instead of the
custom hash function currently used. MurmurHash3 is already used for
the SELinux access vector table so the impact to the code is minimal,
and performance tests have shown improvements in both hash
distribution and latency.

See the commit message for the performance measurments.

- Introduce a Kconfig option for the SELinux AVC bucket/slot size

While we have the ability to grow the number of AVC hash buckets
today, the size of the buckets (slot size) is fixed at 512. This pull
request makes that slot size configurable at build time through a new
Kconfig knob, CONFIG_SECURITY_SELINUX_AVC_HASH_BITS.

selinux: Introduce a new config to make avc cache slot size adjustable

On mobile device high-load situations, permission check can happen
more than 90,000/s (8 core system). With default 512 cache nodes
configuration, avc cache miss happens more often and occasionally
leads to long time (>2ms) irqs off on both big and little cores,
which decreases system real-time capability.

An actual call stack is as follows:
=> avc_compute_av
=> avc_perm_nonode
=> avc_has_perm_noaudit
=> selinux_capable
=> security_capable
=> capable
=> __sched_setscheduler
=> do_sched_setscheduler
=> __arm64_sys_sched_setscheduler
=> invoke_syscall
=> el0_svc_common
=> do_el0_svc
=> el0_svc
=> el0t_64_sync_handler
=> el0t_64_sync

Although we can expand avc nodes through /sys/fs/selinux/cache_threshold
to mitigate long time irqs off, hash conflicts make the bucket average
length longer because of the fixed size of cache slots, leading to
avc_search_node() latency increase.

So introduce a new config to make avc cache slot size also configurable,
and with fine tuning, we can mitigate long time irqs off with slightly
avc_search_node() performance regression.

Theoretically, the main overhead is memory consumption.
