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