#     
#     Pull rseq fixes from Paolo Bonzini:
#      "A fix for a bug with restartable sequences and KVM.
#     
#       KVM's handling of TIF_NOTIFY_RESUME, e.g. for task migration, clears
#       the flag without informing rseq and leads to stale data in userspace's
#       rseq struct"
#     
#     * tag 'for-linus-rseq' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
#       KVM: selftests: Remove __NR_userfaultfd syscall fallback
#       KVM: selftests: Add a test for KVM_RUN+rseq to detect task migration bugs
#       tools: Move x86 syscall number fallbacks to .../uapi/
#       entry: rseq: Call rseq_handle_notify_resume() in tracehook_notify_resume()
