MIPS: Add fast get_user_pages
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.]
