Qualcomm driver updates for v5.18
This refactors the Qualcomm mdt file loader, to partially decouple it
from the SCM peripheral-authentication-service. This is needed as newer
platforms, such as the Qualcomm SM8450, require the metadata to remain
accessible to TrustZone during a longer time. This is followed by the
introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1).
It changes the way hardware version differences are handled in the LLCC
driver and introduces support for Qualcomm SM8450. While updating the dt
binding for LLCC it also introduces the missing SM8350 compatible.
The ocmem and aoss drivers gains missing put_device() calls and rpmpd
gains a missing check for kcalloc() failure.
The SPM driver is updated to avoid instantiating the SPM cpuidle devices
if the CPUs aren't controlled by SPM, such as when Snapdragon 8916
operates in 32-bit mode without PSCI.
The RPM power-domain driver gains MSM8226 support.
Lastly the socinfo driver gains knowledge about a few new SoCs and
PMICs.

Arm SCMI firmware interface updates for v5.18
Few main additions include:
- Support for OPTEE based SCMI transport to enable using SCMI service
provided by OPTEE on some platforms
- Support for atomic SCMI transports which enables few SCMI transactions
to be completed in atomic context. This involves other refactoring work
associated with it. It also marks SMC and OPTEE as atomic transport as
the commands are completed once the return.
- Support for polling mode in SCMI VirtIO transport in order to support
atomic operations
- Support for atomic clock operations based on availability of atomic
capability in the underlying SCMI transport
Other changes involves some trace and log enhancements and miscellaneous
bug fixes.

firmware: arm_scmi: Add a virtio channel refcount
Currently SCMI VirtIO channels are marked with a ready flag and related
lock to track channel lifetime and support proper synchronization at
shutdown when virtqueues have to be stopped.
This leads to some extended spinlocked sections with IRQs off on the RX
path to keep hold of the ready flag and does not scale well especially when
SCMI VirtIO polling mode will be introduced.
Add an SCMI VirtIO channel dedicated refcount to track active users on both
the TX and the RX path and properly enforce synchronization and cleanup at
shutdown, inhibiting further usage of the channel once freed.

tee: simplify shm pool handling
Replaces the shared memory pool based on two pools with a single pool.
The alloc() function pointer in struct tee_shm_pool_ops gets another
parameter, align. This makes it possible to make less than page aligned
allocations from the optional reserved shared memory pool while still
making user space allocations page aligned. With in practice unchanged
behaviour using only a single pool for bookkeeping.
The allocation algorithm in the static OP-TEE shared memory pool is
changed from best-fit to first-fit since only the latter supports an
alignment parameter. The best-fit algorithm was previously the default
choice and not a conscious one.
The optee and amdtee drivers are updated as needed to work with this
changed pool handling.
This also removes OPTEE_SHM_NUM_PRIV_PAGES which becomes obsolete with
this change as the private pages can be mixed with the payload pages.
The OP-TEE driver changes minimum alignment for argument struct from 8
bytes to 512 bytes. A typical OP-TEE private shm allocation is 224 bytes
(argument struct with 6 parameters, needed for open session). So with an
alignment of 512 well waste a bit more than 50%. Before this we had a
single page reserved for this so worst case usage compared to that would
be 3 pages instead of 1 page. However, this worst case only occurs if
there is a high pressure from multiple threads on secure world. All in
all this should scale up and down better than fixed boundaries.

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fix display of grouped aliased events in 'perf stat'.
- Add missing branch_sample_type to perf_event_attr__fprintf().
- Apply correct label to user/kernel symbols in branch mode.
- Fix 'perf ftrace' system_wide tracing, it has to be set before
creating the maps.
- Return error if procfs isn't mounted for PID namespaces when
synthesizing records for pre-existing processes.
- Set error stream of objdump process for 'perf annotate' TUI, to avoid
garbling the screen.
- Add missing arm64 support to perf_mmap__read_self(), the kernel part
got into 5.17.
- Check for NULL pointer before dereference writing debug info about a
sample.
- Update UAPI copies for asound, perf_event, prctl and kvm headers.
- Fix a typo in bpf_counter_cgroup.c.

- Intel/PT: filters could crash the kernel
- Intel: default disable the PMU for SMM, some new-ish EFI firmware has

SMM, meaning that CPL3 (userspace only) events now also count EFI/SMM
cycles.
