Subject: [PATCH 1/2] percpu: unify input section names
Date: Thu, 31 Mar 2011 15:52:01 -0400 [thread overview]
Message-ID: <1301601122-25431-1-git-send-email-vapier@gentoo.org> (raw)
The two percpu helper macros have the section names duplicated. So create
a new define to merge the two. This also allows arches who need to link
things more directly themselves to avoid duplicating the input sections in
their linker script.
