[0/4] mm/gup: some cleanups

Hi Peter, Jason and all,

I'm including Peter's patch as the first one in this tiny series. (The
commit description has my r-b tag in place of my Cc.) The second patch
is what I had in mind for a follow-up to that, when we were discussing
that fix [1].

Plus, a couple more small removals that I had queued up:

The third patch removes a completely unused routine:
pin_user_pages_locked().

The forth patch removes a similar routine, get_user_pages_locked(), that
only has one caller--and that caller is not simplified by calling
get_user_pages_locked().

thanks,
John Hubbard
