Subject: [PATCH RFC 4/9] xen: arm: move setup_virt_paging to p2m.c
Date: Wed, 30 Jul 2014 14:47:12 +0100 [thread overview]
Message-ID: <ecfb533c996af8757cfd630dbed5544fa1e9e3d5.1406728037.git.ian.campbell@citrix.com> (raw)
In-Reply-To: <3ef2b68c511f3e31de409b76757b95c78b99d750.1406728037.git.ian.campbell@citrix.com>
This file is where most of the P2M logic lives and this function will
eventually need to poke at some internals, so move it.
This is pure code motion.
Signed-off-by: Ian Campbell <ian.campbell@citrix.com>
