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

Pull kvm updates from Paolo Bonzini:
"Quite a large pull request due to a selftest API overhaul and some
patches that had come in too late for 5.19.

ARM:

- Unwinder implementations for both nVHE modes (classic and
protected), complete with an overflow stack

- Rework of the sysreg access from userspace, with a complete rewrite
of the vgic-v3 view to allign with the rest of the infrastructure

- Disagregation of the vcpu flags in separate sets to better track
their use model.

- A fix for the GICv2-on-v3 selftest

- A small set of cosmetic fixes

RISC-V:

- Track ISA extensions used by Guest using bitmap

- Added system instruction emulation framework

- Added CSR emulation framework

- Added gfp_custom flag in struct kvm_mmu_memory_cache

- Added G-stage ioremap() and iounmap() functions

- Added support for Svpbmt inside Guest

s390:

- add an interface to provide a hypervisor dump for secure guests

- improve selftests to use TAP interface

- enable interpretive execution of zPCI instructions (for PCI
passthrough)

- First part of deferred teardown

- CPU Topology

- PV attestation

- Minor fixes

x86:

- Permit guests to ignore single-bit ECC errors

- Intel IPI virtualization

- Allow getting/setting pending triple fault with
KVM_GET/SET_VCPU_EVENTS

- PEBS virtualization

- Simplify PMU emulation by just using PERF_TYPE_RAW events

- More accurate event reinjection on SVM (avoid retrying
instructions)

- Allow getting/setting the state of the speaker port data bit

- Refuse starting the kvm-intel module if VM-Entry/VM-Exit controls
are inconsistent

- "Notify" VM exit (detect microarchitectural hangs) for Intel

- Use try_cmpxchg64 instead of cmpxchg64

- Ignore benign host accesses to PMU MSRs when PMU is disabled

- Allow disabling KVM's "MONITOR/MWAIT are NOPs!" behavior

- Allow NX huge page mitigation to be disabled on a per-vm basis

- Port eager page splitting to shadow MMU as well

- Enable CMCI capability by default and handle injected UCNA errors

- Expose pid of vcpu threads in debugfs

- x2AVIC support for AMD

- cleanup PIO emulation

- Fixes for LLDT/LTR emulation

- Don't require refcounted "struct page" to create huge SPTEs

- Miscellaneous cleanups:
- MCE MSR emulation
- Use separate namespaces for guest PTEs and shadow PTEs bitmasks
- PIO emulation
- Reorganize rmap API, mostly around rmap destruction
- Do not workaround very old KVM bugs for L0 that runs with nesting enabled
- new selftests API for CPUID

Generic:

- Fix races in gfn->pfn cache refresh; do not pin pages tracked by
the cache

- new selftests API using struct kvm_vcpu instead of a (vm, id)
tuple"

KVM: selftests: Add TEST_REQUIRE macros to reduce skipping copy+paste

Add TEST_REQUIRE() and __TEST_REQUIRE() to replace the myriad open coded
instances of selftests exiting with KSFT_SKIP after printing an
informational message. In addition to reducing the amount of boilerplate
code in selftests, the UPPERCASE macro names make it easier to visually
identify a test's requirements.

Convert usage that erroneously uses something other than print_skip()
and/or "exits" with '0' or some other non-KSFT_SKIP value.

Intentionally drop a kvm_vm_free() in aarch64/debug-exceptions.c as part
of the conversion. All memory and file descriptors are freed on process
exit, so the explicit free is superfluous.

KVM: selftests: Add kvm_has_cap() to provide syntactic sugar

Add kvm_has_cap() to wrap kvm_check_cap() and return a bool for the use
cases where the caller only wants check if a capability is supported,
i.e. doesn't care about the value beyond whether or not it's non-zero.
The "check" terminology is somewhat ambiguous as the non-boolean return
suggests that '0' might mean "success", i.e. suggests that the ioctl uses
the 0/-errno pattern. Provide a wrapper instead of trying to find a new
name for the raw helper; the "check" terminology is derived from the name
of the ioctl, so using e.g. "get" isn't a clear win.

KVM: selftests: Rename vm_create() => vm_create_barebones(), drop param

Rename vm_create() to vm_create_barebones() and drop the @phys_pages
param. Pass '0' for the number of pages even though some callers pass
'DEFAULT_GUEST_PHY_PAGES', as the intent behind creating truly barebones
VMs is purely to create a VM, i.e. there aren't vCPUs, there's no guest
code loaded, etc..., and so there is nothing that will ever need or
consume guest memory.

Freeing up the name vm_create() will allow using the name for an inner
helper to the other VM creators, which need a "full" VM.

Opportunisticaly rewrite the function comment for addr_gpa2alias() to
focus on what the _function_ does, not what its _sole caller_ does.
