Pull kvm fixes from Paolo Bonzini:

 - Check for invalid flags to KVM_CAP_X86_USER_SPACE_MSR

 - Fix use of sched_setaffinity in selftests

 - Sync kernel headers to tools

 - Fix KVM_STATS_UNIT_MAX

* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  KVM: x86: Protect the unused bits in MSR exiting flags
  tools headers UAPI: Sync linux/kvm.h with the kernel sources
  KVM: selftests: Fix target thread to be migrated in rseq_test
  KVM: stats: Fix value for KVM_STATS_UNIT_MAX for boolean stats
