Subject: [PATCH 1/3] mips: make page.h constants available to assembly.

From: Nelson Elhage <nelhage@...lice.com>

page.h includes ifndef __ASSEMBLY__ guards, but PAGE_SIZE and some other
constants are defined using "1UL", which the assembler does not
support. Use the _AC macro from const.h to make them available to
assembly (and linker scripts).
