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

Pull kvm fixes from Paolo Bonzini:
 "RISC-V:

   - Avoid redundant allocations when allocating IMSIC page tables

   - Apply SBI FWFT LOCK flag only on successful set

   - Bound SBI PMU counter mask scan to BITS_PER_LONG, since on RV32 the
     PMU SBI start/stop helper can only access 32 PMU counters.

   - Skip TLB flush when G-stage PTE becomes valid if the Svvptc
     extension is available.

   - Always show Zicbo[m|z|p] block sizes in ONE_REG

   - Inject instruction access fault on unmapped guest fetch

   - Use raw spinlock for irqs_pending and irqs_pending_mask

   - Fix Spectre-v1 in vector register access via ONE_REG

  x86:

   - Fixes to SEV selftests

   - Once free_nested() did a VMCLEAR of shadow VMCS, there's no need to
     VMCLEAR it again if the kernel is preempted and thread migration
     happens

   - Preserve nested TDP shadow page tables if they are used as roots,
     instead of clearing them unnecessarily

   - Fix use of stale data if out-of-memory happens after vendor module
     reload

   - Check for invalid/obsolete root *after* making MMU pages available,
     because the latter can make a page invalid

   - Only reset TSC Deadline Timer in apic_timer_expired on KVM_RUN"
