#     Pull virtio-mem update from David Hildenbrand:
#      "Support the VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature in virtio-mem,
#       now that "accidential" access to logically unplugged memory inside
#       added Linux memory blocks is no longer possible, because we:
#     
#        - Removed /dev/kmem in commit bbcd53c96071 ("drivers/char: remove
#          /dev/kmem for good")
#     
#        - Disallowed access to virtio-mem device memory via /dev/mem in
#          commit 2128f4e21aa ("virtio-mem: disallow mapping virtio-mem memory
#          via /dev/mem")
#     
#        - Sanitized access to virtio-mem device memory via /proc/kcore in
#          commit 0daa322b8ff9 ("fs/proc/kcore: don't read offline sections,
#          logically offline pages and hwpoisoned pages")
#     
#        - Sanitized access to virtio-mem device memory via /proc/vmcore in
#          commit ce2814622e84 ("virtio-mem: kdump mode to sanitize
#          /proc/vmcore access")
#     
#       The new VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature that will be
#       required by some hypervisors implementing virtio-mem in the near
#       future, so let's support it now that we safely can"
