[1/6] arm64: Fold proc-macros.S into assembler.h

Commit Message

Geoff Levand March 19, 2015, 8:35 p.m. UTC

To allow the assembler macros defined in arch/arm64/mm/proc-macros.S to be used
outside the mm code move the contents of proc-macros.S to asm/assembler.h.  Also,
delete proc-macros.S, and fix up all references to proc-macros.S.
