Hi,

Here are two more patchlets that cleanup mmap_sem and gup abusers.
The second is also a fixlet.

Compile-tested only. Please consider for v5.1

Thanks!

Davidlohr Bueso (2):
  xsk: do not use mmap_sem
  MIPS/c-r4k: do no use mmap_sem for gup_fast()

Unlike what the subject says, this is not against -tip, it applies
on today's -next.
