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 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull KVM updates from Paolo Bonzini:
"ARM:

- Support for userspace handling of synchronous external aborts
(SEAs), allowing the VMM to potentially handle the abort in a
non-fatal manner

- Large rework of the VGIC's list register handling with the goal of
supporting more active/pending IRQs than available list registers
in hardware. In addition, the VGIC now supports EOImode==1 style
deactivations for IRQs which may occur on a separate vCPU than the
one that acked the IRQ

- Support for FEAT_XNX (user / privileged execute permissions) and
FEAT_HAF (hardware update to the Access Flag) in the software page
table walkers and shadow MMU

- Allow page table destruction to reschedule, fixing long
need_resched latencies observed when destroying a large VM

- Minor fixes to KVM and selftests

Loongarch:

- Get VM PMU capability from HW GCFG register

- Add AVEC basic support

- Use 64-bit register definition for EIOINTC

- Add KVM timer test cases for tools/selftests

RISC/V:

- SBI message passing (MPXY) support for KVM guest

- Give a new, more specific error subcode for the case when in-kernel
AIA virtualization fails to allocate IMSIC VS-file

- Support KVM_DIRTY_LOG_INITIALLY_SET, enabling dirty log gradually
in small chunks

- Fix guest page fault within HLV* instructions

- Flush VS-stage TLB after VCPU migration for Andes cores

s390:

- Always allocate ESCA (Extended System Control Area), instead of
starting with the basic SCA and converting to ESCA with the
addition of the 65th vCPU. The price is increased number of exits
(and worse performance) on z10 and earlier processor; ESCA was
introduced by z114/z196 in 2010

- VIRT_XFER_TO_GUEST_WORK support

- Operation exception forwarding support

- Cleanups

x86:

- Skip the costly "zap all SPTEs" on an MMIO generation wrap if MMIO
SPTE caching is disabled, as there can't be any relevant SPTEs to
zap

- Relocate a misplaced export

- Fix an async #PF bug where KVM would clear the completion queue
when the guest transitioned in and out of paging mode, e.g. when
handling an SMI and then returning to paged mode via RSM

- Leave KVM's user-return notifier registered even when disabling
virtualization, as long as kvm.ko is loaded. On reboot/shutdown,
keeping the notifier registered is ok; the kernel does not use the
MSRs and the callback will run cleanly and restore host MSRs if the
CPU manages to return to userspace before the system goes down

- Use the checked version of {get,put}_user()

- Fix a long-lurking bug where KVM's lack of catch-up logic for
periodic APIC timers can result in a hard lockup in the host

- Revert the periodic kvmclock sync logic now that KVM doesn't use a
clocksource that's subject to NTP corrections

- Clean up KVM's handling of MMIO Stale Data and L1TF, and bury the
latter behind CONFIG_CPU_MITIGATIONS

- Context switch XCR0, XSS, and PKRU outside of the entry/exit fast
path; the only reason they were handled in the fast path was to
paper of a bug in the core #MC code, and that has long since been
fixed

- Add emulator support for AVX MOV instructions, to play nice with
emulated devices whose guest drivers like to access PCI BARs with
large multi-byte instructions

x86 (AMD):

- Fix a few missing "VMCB dirty" bugs

- Fix the worst of KVM's lack of EFER.LMSLE emulation

- Add AVIC support for addressing 4k vCPUs in x2AVIC mode

- Fix incorrect handling of selective CR0 writes when checking
intercepts during emulation of L2 instructions

- Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32]
on VMRUN and #VMEXIT

- Fix a bug where KVM corrupt the guest code stream when re-injecting
a soft interrupt if the guest patched the underlying code after the
VM-Exit, e.g. when Linux patches code with a temporary INT3

- Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits
to userspace, and extend KVM "support" to all policy bits that
don't require any actual support from KVM

x86 (Intel):

- Use the root role from kvm_mmu_page to construct EPTPs instead of
the current vCPU state, partly as worthwhile cleanup, but mostly to
pave the way for tracking per-root TLB flushes, and elide EPT
flushes on pCPU migration if the root is clean from a previous
flush

- Add a few missing nested consistency checks

- Rip out support for doing "early" consistency checks via hardware
as the functionality hasn't been used in years and is no longer
useful in general; replace it with an off-by-default module param
to WARN if hardware fails a check that KVM does not perform

- Fix a currently-benign bug where KVM would drop the guest's
SPEC_CTRL[63:32] on VM-Enter

- Misc cleanups

- Overhaul the TDX code to address systemic races where KVM (acting
on behalf of userspace) could inadvertantly trigger lock contention
in the TDX-Module; KVM was either working around these in weird,
ugly ways, or was simply oblivious to them (though even Yan's
devilish selftests could only break individual VMs, not the host
kernel)

- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a
TDX vCPU, if creating said vCPU failed partway through

- Fix a few sparse warnings (bad annotation, 0 != NULL)

- Use struct_size() to simplify copying TDX capabilities to userspace

- Fix a bug where TDX would effectively corrupt user-return MSR
values if the TDX Module rejects VP.ENTER and thus doesn't clobber
host MSRs as expected

Selftests:

- Fix a math goof in mmu_stress_test when running on a single-CPU
system/VM

- Forcefully override ARCH from x86_64 to x86 to play nice with
specifying ARCH=x86_64 on the command line

- Extend a bunch of nested VMX to validate nested SVM as well

- Add support for LA57 in the core VM_MODE_xxx macro, and add a test
to verify KVM can save/restore nested VMX state when L1 is using
5-level paging, but L2 is not

- Clean up the guest paging code in anticipation of sharing the core
logic for nested EPT and nested NPT

guest_memfd:

- Add NUMA mempolicy support for guest_memfd, and clean up a variety
of rough edges in guest_memfd along the way

- Define a CLASS to automatically handle get+put when grabbing a
guest_memfd from a memslot to make it harder to leak references

- Enhance KVM selftests to make it easer to develop and debug
selftests like those added for guest_memfd NUMA support, e.g. where
test and/or KVM bugs often result in hard-to-debug SIGBUS errors

- Misc cleanups

Generic:

- Use the recently-added WQ_PERCPU when creating the per-CPU
workqueue for irqfd cleanup

- Fix a goof in the dirty ring documentation

- Fix choice of target for directed yield across different calls to
kvm_vcpu_on_spin(); the function was always starting from the first
vCPU instead of continuing the round-robin search"

Pull kvm updates from Paolo Bonzini:
"This excludes the bulk of the x86 changes, which I will send
separately. They have two not complex but relatively unusual conflicts
so I will wait for other dust to settle.

guest_memfd:

- Add support for host userspace mapping of guest_memfd-backed memory
for VM types that do NOT use support KVM_MEMORY_ATTRIBUTE_PRIVATE
(which isn't precisely the same thing as CoCo VMs, since x86's
SEV-MEM and SEV-ES have no way to detect private vs. shared).

This lays the groundwork for removal of guest memory from the
kernel direct map, as well as for limited mmap() for
guest_memfd-backed memory.

For more information see:
- commit a6ad54137af9 ("Merge branch 'guest-memfd-mmap' into HEAD")
- guest_memfd in Firecracker:
https://github.com/firecracker-microvm/firecracker/tree/feature/secret-hiding
- direct map removal:
https://lore.kernel.org/all/20250221160728.1584559-1-roypat@amazon.co.uk/
- mmap support:
https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/

ARM:

- Add support for FF-A 1.2 as the secure memory conduit for pKVM,
allowing more registers to be used as part of the message payload.

- Change the way pKVM allocates its VM handles, making sure that the
privileged hypervisor is never tricked into using uninitialised
data.

- Speed up MMIO range registration by avoiding unnecessary RCU
synchronisation, which results in VMs starting much quicker.

- Add the dump of the instruction stream when panic-ing in the EL2
payload, just like the rest of the kernel has always done. This
will hopefully help debugging non-VHE setups.

- Add 52bit PA support to the stage-1 page-table walker, and make use
of it to populate the fault level reported to the guest on failing
to translate a stage-1 walk.

- Add NV support to the GICv3-on-GICv5 emulation code, ensuring
feature parity for guests, irrespective of the host platform.

- Fix some really ugly architecture problems when dealing with debug
in a nested VM. This has some bad performance impacts, but is at
least correct.

- Add enough infrastructure to be able to disable EL2 features and
give effective values to the EL2 control registers. This then
allows a bunch of features to be turned off, which helps cross-host
migration.

- Large rework of the selftest infrastructure to allow most tests to
transparently run at EL2. This is the first step towards enabling
NV testing.

- Various fixes and improvements all over the map, including one BE
fix, just in time for the removal of the feature.

LoongArch:

- Detect page table walk feature on new hardware

- Add sign extension with kernel MMIO/IOCSR emulation

- Improve in-kernel IPI emulation

- Improve in-kernel PCH-PIC emulation

- Move kvm_iocsr tracepoint out of generic code

RISC-V:

- Added SBI FWFT extension for Guest/VM with misaligned delegation
and pointer masking PMLEN features

- Added ONE_REG interface for SBI FWFT extension

- Added Zicbop and bfloat16 extensions for Guest/VM

- Enabled more common KVM selftests for RISC-V

- Added SBI v3.0 PMU enhancements in KVM and perf driver

s390:

- Improve interrupt cpu for wakeup, in particular the heuristic to
decide which vCPU to deliver a floating interrupt to.

- Clear the PTE when discarding a swapped page because of CMMA; this
bug was introduced in 6.16 when refactoring gmap code.

x86 selftests:

- Add #DE coverage in the fastops test (the only exception that's
guest- triggerable in fastop-emulated instructions).

- Fix PMU selftests errors encountered on Granite Rapids (GNR),
Sierra Forest (SRF) and Clearwater Forest (CWF).

- Minor cleanups and improvements

x86 (guest side):

- For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when
overriding guest MTRR for TDX/SNP to fix an issue where ACPI
auto-mapping could map devices as WB and prevent the device drivers
from mapping their devices with UC/UC-.

- Make kvm_async_pf_task_wake() a local static helper and remove its
export.

- Use native qspinlocks when running in a VM with dedicated
vCPU=>pCPU bindings even when PV_UNHALT is unsupported.

Generic:

- Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as
__GFP_NOWARN is now included in GFP_NOWAIT.
