d577cf76fa ALSA: hda: hdmi - fix port numbering for ICL and TGL platforms
Semantics of port#0 differ between ICL and TGL:

 ICL port#0   -> never used for HDAudio
 ICL port#1   -> should be mapped to first pin (0x04)
 TGL port#0   -> typically not used, but HW has the support,
		 so should be mapped to first pin (0x04)
 TGL port#1   -> should be mapped to 2nd pin (0x06)

Refactor the port mapping logic to allow to take the above
differences into account. Fixes issues with HDAudio on some
TGL platforms.

7936a22dd4 drm/i915/gt: Wait for new requests in intel_gt_retire_requests()
Our callers fall into two categories, those passing timeout=0 who just
want to flush request retirements and those passing a timeout that need
to wait for submission completion (e.g. intel_gt_wait_for_idle()).
Currently, we only wait for a snapshot of timelines at the start of the
wait (but there was an expectation that new requests would cause timelines
to appear at the end). However, our callers, such as
intel_gt_wait_for_idle() before suspend, do require us to wait for the
power management requests emitted by retirement as well. If we don't,
then it takes an extra second or two for the background worker to flush
the queue and mark the GT as idle.

5ba03f8f68 rtc: fsl-ftm-alarm: remove select FSL_RCPM and default y from Kconfig
The Flextimer alarm is primarily used as a wakeup source for system
power management.  But it shouldn't select the power management driver
as they don't really have dependency of each other.

Also remove the default y as it is not a critical feature for the
systems.

61005d65b6 HID: logitech-hidpp: Silence intermittent get_battery_capacity errors
My Logitech M185 (PID:4038) 2.4 GHz wireless HID++ mouse is causing
intermittent errors like these in the log:

We are already silencing error-code 0x09 (HIDPP_ERROR_RESOURCE_ERROR)

hidpp20_batterylevel_get_battery_capacity to remove these harmless,
but scary looking errors from the dmesg output.

It is easy to read code if it is cleanly using paired function/naming,

But, current ALSA SoC code is very random, unbalance, not paired, etc.
It is easy to create bug at the such code, and it will be difficult to
debug.

snd_soc_bind_card() is calling snd_soc_dapm_init() for both
card and component.
Let's call paired snd_soc_dapm_shutdown() at paired

ASoC: wm8904: fix regcache handling
The current code assumes that the power is turned off in
SND_SOC_BIAS_OFF. If there are no actual regulator the codec isn't
turned off and the registers are not reset to their default values but
the regcache is still marked as dirty. Thus a value might not be written
to the hardware if it is set to the default value. Do a software reset
before turning off the power to make sure the registers are always reset
to their default states.

vdso-note.o is compiled from the assembly file, vdso-note.S, hence
CFLAGS_REMOVE_vdso-note.o is meaningless.

Neither vvar.c nor vvar.S is found in the vdso directory. Since there
is no source file to create vvar.o, CFLAGS_REMOVE_vvar.o is also
meaningless.

7ee30bc132 KVM: x86: deliver KVM IOAPIC scan request to target vCPUs
In IOAPIC fixed delivery mode instead of flushing the scan
requests to all vCPUs, we should only send the requests to
vCPUs specified within the destination field.

This patch introduces kvm_get_dest_vcpus_mask() API which
retrieves an array of target vCPUs by using
kvm_apic_map_get_dest_lapic() and then based on the
vcpus_idx, it sets the bit in a bitmap. However, if the above
fails kvm_get_dest_vcpus_mask() finds the target vCPUs by
traversing all available vCPUs. Followed by setting the
bits in the bitmap.

If we had different vCPUs in the previous request for the
same redirection table entry then bits corresponding to
these vCPUs are also set. This to done to keep
ioapic_handled_vectors synchronized.

This bitmap is then eventually passed on to
kvm_make_vcpus_request_mask() to generate a masked request
only for the target vCPUs.

This would enable us to reduce the latency overhead on isolated
vCPUs caused by the IPI to process due to KVM_REQ_IOAPIC_SCAN.

8750e72a79 KVM: remember position in kvm->vcpus array
Fetching an index for any vcpu in kvm->vcpus array by traversing
the entire array everytime is costly.
This patch remembers the position of each vcpu in kvm->vcpus array
by storing it in vcpus_idx under kvm_vcpu structure.

662f1d1d19 KVM: nVMX: Add support for capturing highest observable L2 TSC
The L1 hypervisor may include the IA32_TIME_STAMP_COUNTER MSR in the
vmcs12 MSR VM-exit MSR-store area as a way of determining the highest
TSC value that might have been observed by L2 prior to VM-exit. The
current implementation does not capture a very tight bound on this
value.  To tighten the bound, add the IA32_TIME_STAMP_COUNTER MSR to the
vmcs02 VM-exit MSR-store area whenever it appears in the vmcs12 VM-exit
MSR-store area.  When L0 processes the vmcs12 VM-exit MSR-store area
during the emulation of an L2->L1 VM-exit, special-case the
IA32_TIME_STAMP_COUNTER MSR, using the value stored in the vmcs02
VM-exit MSR-store area to derive the value to be stored in the vmcs12
VM-exit MSR-store area.

The "load IA32_PERF_GLOBAL_CTRL" bit for VM-entry and VM-exit should
only be exposed to the guest if IA32_PERF_GLOBAL_CTRL is a valid MSR.
Create a new helper to allow pmu_refresh() to update the VM-Entry and
VM-Exit controls to ensure PMU values are initialized when performing
the is_valid_msr() check.
