#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
#     
#     Pull KVM fixes from Paolo Bonzini:
#      "ARM and x86 bugfixes of all kinds.
#     
#       The most visible one is that migrating a nested hypervisor has always
#       been busted on Broadwell and newer processors, and that has finally
#       been fixed"
