0fe8813baf perf/core: Add RCU read lock protection to perf_iterate_ctx()
The perf_iterate_ctx() function performs RCU list traversal but
currently lacks RCU read lock protection. This causes lockdep warnings
when running perf probe with unshare(1) under CONFIG_PROVE_RCU_LIST=y:

	WARNING: suspicious RCU usage

This protection was previously present but was removed in commit

2428865bf0 KVM: selftests: Add a nested (forced) emulation intercept test for x86
Add a rudimentary test for validating KVM's handling of L1 hypervisor
intercepts during instruction emulation on behalf of L2.  To minimize
complexity and avoid overlap with other tests, only validate KVM's
handling of instructions that L1 wants to intercept, i.e. that generate a
nested VM-Exit.  Full testing of emulation on behalf of L2 is better
achieved by running existing (forced) emulation tests in a VM, (although
on VMX, getting L0 to emulate on #UD requires modifying either L1 KVM to
not intercept #UD, or modifying L0 KVM to prioritize L0's exception
intercepts over L1's intercepts, as is done by KVM for SVM).

Since emulation should never be successful, i.e. L2 always exits to L1,
dynamically generate the L2 code stream instead of adding a helper for
each instruction.  Doing so requires hand coding instruction opcodes, but
makes it significantly easier for the test to compute the expected "next
RIP" and instruction length.

79a14afc60 KVM: nVMX: Synthesize nested VM-Exit for supported emulation intercepts
When emulating an instruction on behalf of L2 that L1 wants to intercept,
generate a nested VM-Exit instead of injecting a #UD into L2.  Now that
(most of) the necessary information is available, synthesizing a VM-Exit
isn't terribly difficult.

Punt on decoding the ModR/M for descriptor table exits for now.  There is
no evidence that any hypervisor intercepts descriptor table accesses *and*
uses the EXIT_QUALIFICATION to expedite emulation, i.e. it's not worth
delaying basic support for.

To avoid doing more harm than good, e.g. by putting L2 into an infinite
or effectively corrupting its code stream, inject #UD if the instruction
length is nonsensical.

fbd1e0f195 KVM: nVMX: Allow the caller to provide instruction length on nested VM-Exit
Rework the nested VM-Exit helper to take the instruction length as a
parameter, and convert nested_vmx_vmexit() into a "default" wrapper that
grabs the length from vmcs02 as appropriate.  This will allow KVM to set
the correct instruction length when synthesizing a nested VM-Exit when
emulating an instruction that L1 wants to intercept.

No functional change intended, as the path to prepare_vmcs12()'s reading
of vmcs02.VM_EXIT_INSTRUCTION_LEN is gated on the same set of conditions
as the VMREAD in the new nested_vmx_vmexit().

9aeb9d8a67 KVM: x86: Plumb the emulator's starting RIP into nested intercept checks
When checking for intercept when emulating an instruction on behalf of L2,
pass the emulator's view of the RIP of the instruction being emulated to
vendor code.  Unlike SVM, which communicates the next RIP on VM-Exit,
VMX communicates the length of the instruction that generated the VM-Exit,
i.e. requires the current and next RIPs.

Note, unless userspace modifies RIP during a userspace exit that requires
completion, kvm_rip_read() will contain the same information.  Pass the
emulator's view largely out of a paranoia, and because there is no
meaningful cost in doing so.

f43f7a215a KVM: nVMX: Emulate HLT in L2 if it's not intercepted
Extend VMX's nested intercept logic for emulated instructions to handle
HLT interception, primarily for testing purposes.  Failure to allow
emulation of HLT isn't all that interesting, as emulating HLT while L2 is
active either requires forced emulation (and no #UD intercept in L1), TLB
games in the guest to coerce KVM into emulating the wrong instruction, or
a bug elsewhere in KVM.

E.g. without commit 47ef3ef843 ("KVM: VMX: Handle event vectoring
error in check_emulate_instruction()"), KVM can end up trying to emulate
HLT if RIP happens to point at a HLT when a vectored event arrives with
L2's IDT pointing at emulated MMIO.

Note, vmx_check_intercept() is still broken when L1 wants to intercept an
instruction, as KVM injects a #UD instead of synthesizing a nested VM-Exit.
That issue extends far beyond HLT, punt on it for now.

on behalf of L2 and L1 _does_ expose RDPID/RDTSCP to L2.  When RDPID

c8e612bfed KVM: nSVM: Pass next RIP, not current RIP, for nested VM-Exit on emulation
Set "next_rip" in the emulation interception info passed to vendor code
using the emulator context's "_eip", not "eip".  "eip" holds RIP from the
start of emulation, i.e. the RIP of the instruction that's being emulated,
whereas _eip tracks the context's current position in decoding the code
stream, which at the time of the intercept checks is effectively the RIP
of the next instruction.

Passing the current RIP as next_rip causes SVM to stuff the wrong value
value into vmcb12->control.next_rip if a nested VM-Exit is generated, i.e.
if L1 wants to intercept the instruction, and could result in L1 putting
L2 into an infinite loop due to restarting L2 with the same RIP over and
over.

f002a97ec8 KVM: nVMX: Check PAUSE_EXITING, not BUS_LOCK_DETECTION, on PAUSE emulation
When emulating PAUSE on behalf of L2, check for interception in vmcs12 by
looking at primary execution controls, not secondary execution controls.
Checking for PAUSE_EXITING in secondary execution controls effectively
results in KVM looking for BUS_LOCK_DETECTION, which KVM doesn't expose to
L1, i.e. is always off in vmcs12, and ultimately results in KVM failing to
"intercept" PAUSE.

Because KVM doesn't handle interception during emulation correctly on VMX,
i.e. the "fixed" code is still quite broken, and not intercepting PAUSE is
relatively benign, for all intents and purposes the bug means that L2 gets
to live when it would otherwise get an unexpected #UD.

than 0x40000000 or 0x40000200.

ASoC: Intel: avs: Add support for mute for PEAKVOL and GAIN
With recent updates to AudioDSP firmware, mute functionality has been
added to PEAKVOL and GAIN modules. The operation occurs over IPC
similarly to how volume is configured. Wire it up to kcontrol
infrastructure present in the avs-driver.

ASoC: Intel: avs: New volume control operations
To provide multi-channel - more than 2 - capability to volume controls
implement operations that honor the num_channels of a mixer control. As
mc->num_channels can be 0 and is in fact the default behavior, the new
functions decide between ALL_CHANNELS_MASK and individual channels based
on the field value.

To avoid hard-to-review delta when refactoring the code, first implement
the new behavior with follow up changes cleaning things up.

ASoC: Intel: avs: Update VOLUME and add MUTE IPCs
For mute kcontrols to have an effect add IPCs for triggering the mute
operation on the DSP side. On top of basic get/set, an aggregated
variant of the latter is provided for both MUTE and, to already present
VOLUME IPC. It allows for efficient transmission of multiple parameters
at once.

While at it, sort the functions - getters come before setters in the
AudioDSP firmware interface as well as in the kcontrol one.

ASoC: topology: Create kcontrols based on their type
Fields ->ops.info and ->type of struct snd_soc_tplg_ctl_hdr denote
info-operation type and control type respectively. These are two
different pieces of information. The info type is represented by
SND_SOC_TPLG_CTL_xxx and SND_SOC_TPLG_DAPM_CTL_xxx on UAPI side whereas
for control type it is SND_SOC_TPLG_TYPE_xxx (mixer, bytes or enum).

The type of the kcontrol to be created is currently guessed based on the
value of the ->ops.info. Use the ->type instead to correct and simplify
the code. With this change ops.info() can be customized by sound drivers
utilizing the ASoC-topology just like ops.get() and ops.put() can be.

e180a01bf2 wifi: ath12k: Add NULL check to validate tpc_stats
While processing TPC stats received from firmware, there are chances that
the tpc_stats might not be filled and the data is not available. This can
happen under two scenarios. First, when firmware sends a non-zero event
count before event count 0. When this happens, tpc_stats will be checked
for data before memory allocation and the tpc_stats will be unavailable.
Second, when memory allocation failed when event count received is 0 and
the firmware still sends a non-zero event. When this happens, memory will
not be allocated for tpc_stats though event count is 0, so when non-zero
event count is received, tpc_stats will be empty. There are checks to
validate if tpc_stats variable is filled that are used in two subsequent
places, but these are placed after tpc_stats is dereference without
checking if it is NULL or has valid data.

Fix this by removing the mentioned checks and adding a NULL check after
assigning tpc_stats to check if it is valid.

with link specific bss_conff, but missed one instance in

regulator: Add (devm_)of_regulator_get()
The Rockchip power-domain controller also plans to make use of
per-domain regulators similar to the MediaTek power-domain controller.
Since existing DTs are missing the regulator information, the kernel
should fallback to the automatically created dummy regulator if
necessary. Thus the version without the _optional suffix is needed.

The Rockchip driver plans to use the managed version, but to be
consistent with existing code the unmanaged version is added at the
same time.

This was attempted to be fixed in commit b47834ee44 ("ASoC: SOF: amd:

in another config.

Instead move the `depends on AMD_NODE` out of SND_SOC_SOF_AMD_COMMON to
