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

Pull kvm fixes from Paolo Bonzini:
 "x86:

   - Account for family 17h event renumberings in AMD PMU emulation

   - Remove CPUID leaf 0xA on AMD processors

   - Fix lockdep issue with locking all vCPUs

   - Fix loss of A/D bits in SPTEs

   - Fix syzkaller issue with invalid guest state"

* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  KVM: VMX: Exit to userspace if vCPU has injected exception and invalid state
  KVM: SEV: Mark nested locking of vcpu->lock
  kvm: x86/cpuid: Only provide CPUID leaf 0xA if host has architectural PMU
  KVM: x86/svm: Account for family 17h event renumberings in amd_pmc_perf_hw_id
  KVM: x86/mmu: Use atomic XCHG to write TDP MMU SPTEs with volatile bits
  KVM: x86/mmu: Move shadow-present check out of spte_has_volatile_bits()
  KVM: x86/mmu: Don't treat fully writable SPTEs as volatile (modulo A/D)
