From: "H. Peter Anvin (Intel)" <hpa@zytor.com>
This patchset adds the following improvements to <asm/asm.h>:
1. Makes the __ASM_FORM() macros accept arguments with commas. This allows the __ASM_FORM() macros to be used directly in header files for macros that can be used from either C or assembly, even for instructions that have multiple operands. 2. Add an _ASM_BYTES() macro for the delicate job of hand-crafting instructions out of bytes. 3. Replace the _ASM_MK_NOPS() macro in <asm/nops.h> with _ASM_BYTES().
The change to the tools/ directory is mainly because <asm/nops.h> now depends on <asm/asm.h>.
