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

Pull kvm updates from Paolo Bonzini:
"s390:

- More phys_to_virt conversions

- Improvement of AP management for VSIE (nested virtualization)

ARM64:

- Numerous fixes for the pathological lock inversion issue that
plagued KVM/arm64 since... forever.

- New framework allowing SMCCC-compliant hypercalls to be forwarded
to userspace, hopefully paving the way for some more features being
moved to VMMs rather than be implemented in the kernel.

- Large rework of the timer code to allow a VM-wide offset to be
applied to both virtual and physical counters as well as a
per-timer, per-vcpu offset that complements the global one. This
last part allows the NV timer code to be implemented on top.

- A small set of fixes to make sure that we don't change anything
affecting the EL1&0 translation regime just after having having
taken an exception to EL2 until we have executed a DSB. This
ensures that speculative walks started in EL1&0 have completed.

- The usual selftest fixes and improvements.

x86:

- Optimize CR0.WP toggling by avoiding an MMU reload when TDP is
enabled, and by giving the guest control of CR0.WP when EPT is
enabled on VMX (VMX-only because SVM doesn't support per-bit
controls)

- Add CR0/CR4 helpers to query single bits, and clean up related code
where KVM was interpreting kvm_read_cr4_bits()'s "unsigned long"
return as a bool

- Move AMD_PSFD to cpufeatures.h and purge KVM's definition

- Avoid unnecessary writes+flushes when the guest is only adding new
PTEs

- Overhaul .sync_page() and .invlpg() to utilize .sync_page()'s
optimizations when emulating invalidations

- Clean up the range-based flushing APIs

- Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a
single A/D bit using a LOCK AND instead of XCHG, and skip all of
the "handle changed SPTE" overhead associated with writing the
entire entry

- Track the number of "tail" entries in a pte_list_desc to avoid
having to walk (potentially) all descriptors during insertion and
deletion, which gets quite expensive if the guest is spamming
fork()

- Disallow virtualizing legacy LBRs if architectural LBRs are
available, the two are mutually exclusive in hardware

- Disallow writes to immutable feature MSRs (notably
PERF_CAPABILITIES) after KVM_RUN, similar to CPUID features

- Overhaul the vmx_pmu_caps selftest to better validate
PERF_CAPABILITIES

- Apply PMU filters to emulated events and add test coverage to the
pmu_event_filter selftest

- AMD SVM:
- Add support for virtual NMIs
- Fixes for edge cases related to virtual interrupts

- Intel AMX:
- Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if
XTILE_DATA is not being reported due to userspace not opting in
via prctl()
- Fix a bug in emulation of ENCLS in compatibility mode
- Allow emulation of NOP and PAUSE for L2
- AMX selftests improvements
- Misc cleanups

MIPS:

- Constify MIPS's internal callbacks (a leftover from the hardware
enabling rework that landed in 6.3)

Generic:

- Drop unnecessary casts from "void *" throughout kvm_main.c

- Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the
struct size by 8 bytes on 64-bit kernels by utilizing a padding
hole

Documentation:

- Fix goof introduced by the conversion to rST"

: written
:
: - allow a VMM to save/restore the physical timer context, something
: that we cannot do at the moment due to the lack of offsetting
:
: - provide a framework that is suitable for NV support, where we get
: both global and per timer, per vcpu offsetting, and manage
: interrupts in a less braindead way.
:
: Conflict resolution involves using the new per-vcpu config lock instead
: of the home-grown timer lock.

With ECV and CNTPOFF_EL2, it is very easy to offer an offset for
the physical timer. So let's do just that.

Nothing can set the offset yet, so this should have no effect
whatsoever (famous last words...).
