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

Pull kvm fixes from Paolo Bonzini:
 "The main and larger change here is a workaround for AMD's lack of
  cache coherency for encrypted-memory guests.

  I have another patch pending, but it's waiting for review from the
  architecture maintainers.

  RISC-V:

   - Remove 's' & 'u' as valid ISA extension

   - Do not allow disabling the base extensions 'i'/'m'/'a'/'c'

  x86:

   - Fix NMI watchdog in guests on AMD

   - Fix for SEV cache incoherency issues

   - Don't re-acquire SRCU lock in complete_emulated_io()

   - Avoid NULL pointer deref if VM creation fails

   - Fix race conditions between APICv disabling and vCPU creation

   - Bugfixes for disabling of APICv

   - Preserve BSP MSR_KVM_POLL_CONTROL across suspend/resume

  selftests:

   - Do not use bitfields larger than 32-bits, they differ between GCC
     and clang"
