Merge series from Mario Limonciello <superm1@kernel.org>:
The various AMD audio drivers have self contained implementations
for SMN router communication that require hardcoding the bridge ID.
These implementations also don't prevent race conditions with other
drivers performing SMN communication.
A new centralized driver AMD_NODE is introduced and all drivers in
the kernel should use this instead. Adjust all AMD audio drivers to
use it.
Merge series from broonie@kernel.org:
This is a random subset of the patches for the tas2764 driver that I
found in the Asahi Linux tree which seemed to be clear fixes and
improvements which apply easily to mainline without much effort, there's
a bunch more work on the driver that should also be applicable.
I've only build tested this.
Offsets 0x60 and 0x64 are used internally by kernel drivers that call
the amd_smn_read() and amd_smn_write() functions. If userspace accesses
the regions at the same time as the kernel it may cause malfunctions in
drivers using the offsets.
Add these offsets to the exclusions so that the kernel is tainted if a
non locked down userspace tries to access them.

When we shut down the amp, we need to wait for the built-in ramp-down
before we can remove the TDM clocks. There is no documented status
regiter to poll, so the best we can do is a delay. Datasheet says 5.9ms
for ramp-down and 1.5ms between shutdown and next startup, so let's do
6ms after mute and 2ms after shutdown. That gives us a cumulative 8ms
for ramp-down and guaratees the required minimum shutdown time.

The ASoC convention is that clocks are removed after codec mute, and
power up/down is more about top level power management. For these chips,
the "mute" state still expects a TDM clock, and yanking the clock in
this state will trigger clock errors. So, do the full
shutdown<->mute<->active transition on the mute operation, so the amp is
in software shutdown by the time the clocks are removed.
This fixes TDM clock errors when streams are stopped.

DPCM is already difficult to read, but now dpcm_dai_trigger_fe_be() even
difficult to read.
static int dpcm_dai_trigger_fe_be(.., fe_first)
{
^ if (fe_first) {
(A) ...
|(x) goto end;
v }
^
(B) ...
v
end:
return ...
}
It want to switch function call order by using "fe_first" for fe->be
order part (A), or be->fe order part (B). But the code is using "goto"
in last of (A) (=x).
Just use "if..else" for (A) (B) is easy to read and understand what it
want to do.
static int dpcm_dai_trigger_fe_be(.., fe_first)
{
^ if (fe_first) {
(A) ...
v }
^ else {
(B) ...
v }
return ...
}

dpcm_process_paths() will call dpcm_add_paths() (A) or
dpcm_prune_paths() (B)
dpcm_process_paths(..., new)
{
if (new)
(A) return dpcm_add_paths(...);
else
(B) return dpcm_prune_paths(...);
}
but the user who need to call dpcm_prune_paths() (B) is only
soc_dpcm_fe_runtime_update(), all other user want to call is
dpcm_add_paths() (A). We don't need to have confusing
dpcm_process_paths(). Let's remove it.

Pull driver core api addition from Greg KH:
"Here is a driver core new api for 6.14-rc3 that is being added to
allow platform devices from stop being abused.
It adds a new 'faux_device' structure and bus and api to allow almost
a straight or simpler conversion from platform devices that were not
really a platform device. It also comes with a binding for rust, with
an example driver in rust showing how it's used.
I'm adding this now so that the patches that convert the different
drivers and subsystems can all start flowing into linux-next now
through their different development trees, in time for 6.15-rc1.
We have a number that are already reviewed and tested, but adding
those conversions now doesn't seem right. For now, no one is using
this, and it passes all build tests from 0-day and linux-next, so all
should be good"

- Large set of fixes for vector handling, especially in the

This fixes a number of bugs affecting actual deployments, and
greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland
for dealing with this thankless task.
- Fix an ugly race between vcpu and vgic creation/init, resulting in
unexpected behaviours
- Fix use of kernel VAs at EL2 when emulating timers with nVHE
- Small set of pKVM improvements and cleanups
x86:
- Fix broken SNP support with KVM module built-in, ensuring the PSP
module is initialized before KVM even when the module
infrastructure cannot be used to order initcalls
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being
emulated by KVM to fix a NULL pointer dereference
- Enter guest mode (L2) from KVM's perspective before initializing
the vCPU's nested NPT MMU so that the MMU is properly tagged for
L2, not L1
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as
the guest's value may be stale if a VM-Exit is handled in the
