Subject: [PATCH 23/45] C++: Don't do "extern asmlinkage"
Date: Sun, 01 Apr 2018 21:42:33 +0100	[thread overview]
Message-ID: <152261535374.30503.17167565394146100518.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <152261521484.30503.16131389653845029164.stgit@warthog.procyon.org.uk>

Don't do "extern asmlinkage" as asmlinkage is defined to include extern
"C".

Signed-off-by: David Howells <dhowells@redhat.com>
