Subject: [PATCH 2/8] x86/asm: Make asm/alternative.h safe from assembly
Date: Tue, 26 Apr 2016 12:23:25 -0700	[thread overview]
Message-ID: <e5b693fcef99fe6e80341c9e97a002fb23871e91.1461698311.git.luto@kernel.org> (raw)
In-Reply-To: <cover.1461698311.git.luto@kernel.org>
In-Reply-To: <cover.1461698311.git.luto@kernel.org>

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