Merge tag 'uuid-for-4.13' of git://git.infradead.org/users/hch/uuid

Pull uuid subsystem from Christoph Hellwig:
 "This is the new uuid subsystem, in which Amir, Andy and I have started
  consolidating our uuid/guid helpers and improving the types used for
  them. Note that various other subsystems have pulled in this tree, so
  I'd like it to go in early.

  UUID/GUID summary:

   - introduce the new uuid_t/guid_t types that are going to replace the
     somewhat confusing uuid_be/uuid_le types and make the terminology
     fit the various specs, as well as the userspace libuuid library.
     (me, based on a previous version from Amir)

   - consolidated generic uuid/guid helper functions lifted from XFS and
     libnvdimm (Amir and me)

   - conversions to the new types and helpers (Amir, Andy and me)"
