[PATCH 3.2 055/104] x86/asm: Make asm/alternative.h safe from assembly

[Ben Hutchings]

3.2.101-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Andy Lutomirski <luto@xxxxxxxxxx>

commit f005f5d860e0231fe212cfda8c1a3148b99609f4 upstream.

asm/alternative.h isn't directly useful from assembly, but it
shouldn't break the build.
