	Stephen Rothwell reported that the objtool cross-build breaks on non-x86 hosts: > tools/arch/x86/include/asm/asm.h:185:24: error: invalid register name for 'current_stack_pointer' > 185 \| register unsigned long current_stack_pointer asm(_ASM_SP); > \| ^~~~~~~~~~~~~~~~~~~~~ The PowerPC host obviously doesn't know much about x86 register names. Protect the kernel-specific bits of <asm/asm.h>, so that it can be included by tooling and cross-built. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Reviewed-by: H.

	Use the new generalized _ASM_BYTES() macro from <asm/asm.h> instead of the "home grown" _ASM_MK_NOP() in <asm/nops.h>. Add <asm/asm.h> and update <asm/nops.h> in the tools directory...
