Andrew, this asm-compat.h patch should be replaced by the asm.h patch
from Peter. Here it is, straight from the x86 merge git repository :


From: H. Peter Anvin <hpa@zytor.com>
Date: Fri, 2 Nov 2007 20:59:47 +0000 (-0700)
Subject: x86: add <asm/asm.h>
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fhpa%2Flinux-2.6-x86-headermerge.git;a=...

x86: add <asm/asm.h>

Create <asm/asm.h>, with common definitions suitable for assembly
unification.
