[PATCH 3.18 26/47] MIPS: asm: compiler: Add new macros to set ISA and arch asm annotations

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Markos Chandras <markos.chandras@xxxxxxxxxx>

commit be5136988e25ae0dc8379fcb937efc63d87aba9e upstream.

There are certain places where the code uses .set mips32 or .set mips64
or .set arch=r4000. In preparation of MIPS R6 support, and in order to
use as less #ifdefs as possible, we define new macros to set similar
annotations for MIPS R6.
