ASoC: Fixes for v7.1

Another batch of fixes, plus a couple of quirks (mostly AMD ones, as has
been the case recently). All driver changes, including fixes for the
KUnit tests for the Cirrus drivers that could cause memory corruption.

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

Pull kvm updates from Paolo Bonzini:
"On top of a lot of Arm fixes, this includes a massive rename of types
and variables in tools/testing/selftests/kvm - these were
unnecessarily different from what the kernel uses, so they're being
made consistent.

arm64:

- Allow tracing for non-pKVM, which was accidentally disabled when
the series was merged

- Rationalise the way the pKVM hypercall ranges are defined by using
the same mechanism as already used for the vcpu_sysreg enum

- Enforce that SMCCC function numbers relayed by the pKVM proxy are
actually compliant with the specification

- Fix a couple of feature to idreg mappings which resulted in the
wrong sanitisation being applied

- Fix the GICD_IIDR revision number field that could never been
written correctly by userspace

- Make kvm_vcpu_initialized() correctly use its parameter instead of
relying on the surrounding context

- Enforce correct ordering in __pkvm_init_vcpu(), plugging a
potential pin leak at the same time

- Move __pkvm_init_finalise() to a less dangerous spot, avoiding
future problems

- Restore functional userspace irqchip support after a four year
breakage (last functional kernel was 5.18...)

- Spelling fixes

Selftests:

- Rename types across all KVM selftests to more closely align with
types used in the kernel:

vm_vaddr_t -> gva_t
vm_paddr_t -> gpa_t

uint64_t -> u64
uint32_t -> u32
uint16_t -> u16
uint8_t -> u8

int64_t -> s64
int32_t -> s32
int16_t -> s16
int8_t -> s8

- Fix Loongarch compilation"

Merge tag 'kvm-x86-selftests_kernel_types-7.1' of https://github.com/kvm-x86/linux into HEAD

Merge tag 'kvm-x86-selftests_kernel_types-7.1' of https://github.com/kvm-x86/linux into HEAD

KVM selftests type renames for 7.1

Renames types across all KVM selftests to more closely align with types used
in the kernel:

vm_vaddr_t -> gva_t
vm_paddr_t -> gpa_t

uint64_t -> u64
uint32_t -> u32
uint16_t -> u16
uint8_t -> u8

int64_t -> s64
int32_t -> s32
int16_t -> s16
int8_t -> s8

Using the kernel's preferred types eliminates a source of friction for many
contributors, as the majority of KVM selftests contributions come from kernel
developers. The kernel names are also shorter, which allows for more concise
code, and in any many cases eliminates newlines thanks to shorter types and
parameter names.

Rename variables and parameters as well as types, e.g. gpa instead of paddr,
to again align with the kernel, and in a few cases to remove ambiguity, e.g.
where paddr is used to refer to a _host_ physical address.

headers (especially kvm_util_types.h) should have already been including
stdint.h to get uint64_t from the libc headers, but the missing dependency
only rears its head once KVM uses u64 instead of uint64_t.

Pull more kvm updates from Paolo Bonzini:
Generic:

- Clean up locking of all vCPUs for a VM by using the *_nest_lock()
family of functions, and move duplicated code to virt/kvm/. kernel/
patches acked by Peter Zijlstra

- Add MGLRU support to the access tracking perf test

ARM fixes:

- Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change

- Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o
private IRQs allocated

- Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum

- Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping

- Avoid dereferencing a NULL pointer in the VGIC debug code, which
can happen if the device doesn't have any mapping yet

s390:

- Fix interaction between some filesystems and Secure Execution

- Some cleanups and refactorings, preparing for an upcoming big
series

x86:

- Wait for target vCPU to ack KVM_REQ_UPDATE_PROTECTED_GUEST_STATE
to fix a race between AP destroy and VMRUN

- Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for
the VM

- Refine and harden handling of spurious faults

- Add support for ALLOWED_SEV_FEATURES

- Add #VMGEXIT to the set of handlers special cased for
CONFIG_RETPOLINE=y

- Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing
features that utilize those bits

- Don't account temporary allocations in sev_send_update_data()

- Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock
Threshold

- Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU
IBPB, between SVM and VMX

- Advertise support to userspace for WRMSRNS and PREFETCHI

- Rescan I/O APIC routes after handling EOI that needed to be
intercepted due to the old/previous routing, but not the
new/current routing

- Add a module param to control and enumerate support for device
posted interrupts

- Fix a potential overflow with nested virt on Intel systems running
32-bit kernels

- Flush shadow VMCSes on emergency reboot

- Add support for SNP to the various SEV selftests

- Add a selftest to verify fastops instructions via forced emulation

- Refine and optimize KVM's software processing of the posted
interrupt bitmap, and share the harvesting code between KVM and the
kernel's Posted MSI handler"

Merge branch 'for-6.15/amd_sfh' into for-linus

From: Mario Limonciello <mario.limonciello@amd.com>

Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.

Example use cases are "wake from suspend on approach" or to "lock
when leaving".

This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.

Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

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

Pull kvm updates from Paolo Bonzini:
"Loongarch:

- Clear LLBCTL if secondary mmu mapping changes

- Add hypercall service support for usermode VMM

x86:

- Add a comment to kvm_mmu_do_page_fault() to explain why KVM
performs a direct call to kvm_tdp_page_fault() when RETPOLINE is
enabled

- Ensure that all SEV code is compiled out when disabled in Kconfig,
even if building with less brilliant compilers

- Remove a redundant TLB flush on AMD processors when guest CR4.PGE
changes

- Use str_enabled_disabled() to replace open coded strings

- Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's
APICv cache prior to every VM-Enter

- Overhaul KVM's CPUID feature infrastructure to track all vCPU
capabilities instead of just those where KVM needs to manage state
and/or explicitly enable the feature in hardware. Along the way,
refactor the code to make it easier to add features, and to make it
more self-documenting how KVM is handling each feature

- Rework KVM's handling of VM-Exits during event vectoring; this
plugs holes where KVM unintentionally puts the vCPU into infinite
loops in some scenarios (e.g. if emulation is triggered by the
exit), and brings parity between VMX and SVM

- Add pending request and interrupt injection information to the
kvm_exit and kvm_entry tracepoints respectively

- Fix a relatively benign flaw where KVM would end up redoing RDPKRU
when loading guest/host PKRU, due to a refactoring of the kernel
helpers that didn't account for KVM's pre-checking of the need to
do WRPKRU

- Make the completion of hypercalls go through the complete_hypercall
function pointer argument, no matter if the hypercall exits to
userspace or not.

Previously, the code assumed that KVM_HC_MAP_GPA_RANGE specifically
went to userspace, and all the others did not; the new code need
not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at
all whether there was an exit to userspace or not

- As part of enabling TDX virtual machines, support support
separation of private/shared EPT into separate roots.

When TDX will be enabled, operations on private pages will need to
go through the privileged TDX Module via SEAMCALLs; as a result,
they are limited and relatively slow compared to reading a PTE.

The patches included in 6.14 allow KVM to keep a mirror of the
private EPT in host memory, and define entries in kvm_x86_ops to
operate on external page tables such as the TDX private EPT

- The recently introduced conversion of the NX-page reclamation
kthread to vhost_task moved the task under the main process. The
task is created as soon as KVM_CREATE_VM was invoked and this, of
course, broke userspace that didn't expect to see any child task of
the VM process until it started creating its own userspace threads.

In particular crosvm refuses to fork() if procfs shows any child
task, so unbreak it by creating the task lazily. This is arguably a
userspace bug, as there can be other kinds of legitimate worker
tasks and they wouldn't impede fork(); but it's not like userspace
has a way to distinguish kernel worker tasks right now. Should they
show as "Kthread: 1" in proc/.../status?

x86 - Intel:

- Fix a bug where KVM updates hardware's APICv cache of the highest
ISR bit while L2 is active, while ultimately results in a
hardware-accelerated L1 EOI effectively being lost

- Honor event priority when emulating Posted Interrupt delivery
during nested VM-Enter by queueing KVM_REQ_EVENT instead of
immediately handling the interrupt

- Rework KVM's processing of the Page-Modification Logging buffer to
reap entries in the same order they were created, i.e. to mark gfns
dirty in the same order that hardware marked the page/PTE dirty

- Misc cleanups

Generic:

- Cleanup and harden kvm_set_memory_region(); add proper lockdep
assertions when setting memory regions and add a dedicated API for
setting KVM-internal memory regions. The API can then explicitly
disallow all flags for KVM-internal memory regions

- Explicitly verify the target vCPU is online in kvm_get_vcpu() to
fix a bug where KVM would return a pointer to a vCPU prior to it
being fully online, and give kvm_for_each_vcpu() similar treatment
to fix a similar flaw

- Wait for a vCPU to come online prior to executing a vCPU ioctl, to
fix a bug where userspace could coerce KVM into handling the ioctl
on a vCPU that isn't yet onlined

- Gracefully handle xarray insertion failures; even though such
failures are impossible in practice after xa_reserve(), reserving
an entry is always followed by xa_store() which does not know (or
differentiate) whether there was an xa_reserve() before or not

RISC-V:

- Zabha, Svvptc, and Ziccrse extension support for guests. None of
them require anything in KVM except for detecting them and marking
them as supported; Zabha adds byte and halfword atomic operations,
while the others are markers for specific operation of the TLB and
of LL/SC instructions respectively

- Virtualize SBI system suspend extension for Guest/VM

- Support firmware counters which can be used by the guests to
collect statistics about traps that occur in the host

Selftests:

- Rework vcpu_get_reg() to return a value instead of using an
out-param, and update all affected arch code accordingly

- Convert the max_guest_memory_test into a more generic
mmu_stress_test. The basic gist of the "conversion" is to have the
test do mprotect() on guest memory while vCPUs are accessing said
memory, e.g. to verify KVM and mmu_notifiers are working as
intended

- Play nice with treewrite builds of unsupported architectures, e.g.
arm (32-bit), as KVM selftests' Makefile doesn't do anything to
ensure the target architecture is actually one KVM selftests
supports

- Use the kernel's $(ARCH) definition instead of the target triple
for arch specific directories, e.g. arm64 instead of aarch64,
mainly so as not to be different from the rest of the kernel

- Ensure that format strings for logging statements are checked by
the compiler even when the logging statement itself is disabled

- Attempt to whack the last LLC references/misses mole in the Intel
PMU counters test by adding a data load and doing CLFLUSH{OPT} on
the data instead of the code being executed. It seems that modern
Intel CPUs have learned new code prefetching tricks that bypass the
PMU counters

- Fix a flaw in the Intel PMU counters test where it asserts that
events are counting correctly without actually knowing what the
events count given the underlying hardware; this can happen if
Intel reuses a formerly microarchitecture-specific event encoding
as an architectural event, as was the case for Top-Down Slots"
