Subject: [PATCH 02/13] x86/paravirt: Fix output constraint macro names
Date: Wed,  4 Oct 2017 10:58:23 -0500	[thread overview]
Message-ID: <f8aad6bc7bcdb606b89f3d5dc5fb2303019cb3d0.1507128293.git.jpoimboe__44467.4266073436$1509079588$gmane$org@redhat.com> (raw)
In-Reply-To: <cover.1507128293.git.jpoimboe@redhat.com>

Some of the paravirt '*_CLOBBERS' macros refer to output constraints
instead of clobbers, which makes the code extra confusing.  Rename the
output constraint related macros to '*_OUTPUTS'.
