Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"It's a bit larger than I (and probably you) would like by the time we
get to -rc6, but perhaps not entirely unexpected since the changes in
the last merge window were larger than usual.
x86:
- Fixes for missing TLB flushes with TDP MMU
- Fixes for race conditions in nested SVM
- Fixes for lockdep splat with Xen emulation
- Fix for kvmclock underflow
- Fix srcdir != builddir builds
- Other small cleanups
ARM:
- Fix GICv3 MMIO compatibility probing
- Prevent guests from using the ARMv8.4 self-hosted tracing
extension"
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
selftests: kvm: Check that TSC page value is small after KVM_SET_CLOCK(0)
KVM: x86: Prevent 'hv_clock->system_time' from going negative in kvm_guest_time_update()
KVM: x86: disable interrupts while pvclock_gtod_sync_lock is taken
KVM: x86: reduce pvclock_gtod_sync_lock critical sections
KVM: SVM: ensure that EFER.SVME is set when running nested guest or on nested vmexit
KVM: SVM: load control fields from VMCB12 before checking them
KVM: x86/mmu: Don't allow TDP MMU to yield when recovering NX pages
KVM: x86/mmu: Ensure TLBs are flushed for TDP MMU during NX zapping
KVM: x86/mmu: Ensure TLBs are flushed when yielding during GFN range zap
KVM: make: Fix out-of-source module builds
selftests: kvm: make hardware_disable_test less verbose
KVM: x86/vPMU: Forbid writing to MSR_F15H_PERF MSRs when guest doesn't have X86_FEATURE_PERFCTR_CORE
KVM: x86: remove unused declaration of kvm_write_tsc()
KVM: clean up the unused argument
tools/kvm_stat: Add restart delay
KVM: arm64: Fix CPU interface MMIO compatibility detection
KVM: arm64: Disable guest access to trace filter controls
KVM: arm64: Hide system instruction access to Trace registers
