Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

See commit b6999b191 which did the same modification for x86's mm/gup,
Quote from commit b6999b191:
"If compound pages are used and the page is a
tail page, gup_huge_pmd() increases _mapcount to record tail page are
mapped while gup_huge_pud does not do that."
[ralf@linux-mips.org: fixed rejects caused by the original patch getting
linewrapped.]

Gup is used in a few cases, say futex.
This work is derived from the x86 version, and operations of pte and pmd are
adapted to the defines of MIPS in straight forward manner.
[ralf@linux-mips.org: Fixed up reject in arch/mips/mm/Makefile due to
whitespace formatting differences. Fixed build error in gup.c due to
conflicting changes elsewhere in the kernel.]
