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
