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

Pull kvm updates from Paolo Bonzini:
"ARM64:

- Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.

- Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.

- Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
option, which multi-process VMMs such as crosvm rely on (see merge
commit 382b5b87a97d: "Fix a number of issues with MTE, such as
races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").

- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.

- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.

- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.

- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.

s390:

- Second batch of the lazy destroy patches

- First batch of KVM changes for kernel virtual != physical address
support

- Removal of a unused function

x86:

- Allow compiling out SMM support

- Cleanup and documentation of SMM state save area format

- Preserve interrupt shadow in SMM state save area

- Respond to generic signals during slow page faults

- Fixes and optimizations for the non-executable huge page errata
fix.

- Reprogram all performance counters on PMU filter change

- Cleanups to Hyper-V emulation and tests

- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)

- Advertise several new Intel features

- x86 Xen-for-KVM:

- Allow the Xen runstate information to cross a page boundary

- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured

- Add support for 32-bit guests in SCHEDOP_poll

- Notable x86 fixes and cleanups:

- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).

- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.

- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.

- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.

- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.

- Advertise (on AMD) that the SMM_CTL MSR is not supported

- Remove unnecessary exports

Generic:

- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks

Selftests:

- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.

- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.

- Introduce actual atomics for clear/set_bit() in selftests

- Add support for pinning vCPUs in dirty_log_perf_test.

- Rename the so called "perf_util" framework to "memstress".

- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.

- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.

- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).

- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.

- x86-specific selftest changes:

- Clean up x86's page table management.

- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.

- Clean up the nEPT support checks.

- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.

- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
before the test opts in via prctl().

Documentation:

- Remove deleted ioctls from documentation

- Clean up the docs for the x86 MSR filter.

- Various fixes"

series

- A shared branch with the arm64 tree that repaints all the system
registers to match the ARM ARM's naming, and resulting in
interesting conflicts

KVM: Support dirty ring in conjunction with bitmap

ARM64 needs to dirty memory outside of a VCPU context when VGIC/ITS is
enabled. It's conflicting with that ring-based dirty page tracking always
requires a running VCPU context.

Introduce a new flavor of dirty ring that requires the use of both VCPU
dirty rings and a dirty bitmap. The expectation is that for non-VCPU
sources of dirty memory (such as the VGIC/ITS on arm64), KVM writes to
the dirty bitmap. Userspace should scan the dirty bitmap before migrating
the VM to the target.

Use an additional capability to advertise this behavior. The newly added
capability (KVM_CAP_DIRTY_LOG_RING_WITH_BITMAP) can't be enabled before
KVM_CAP_DIRTY_LOG_RING_ACQ_REL on ARM64. In this way, the newly added
capability is treated as an extension of KVM_CAP_DIRTY_LOG_RING_ACQ_REL.
