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