Subject: [PATCH 04/20] powerpc/powernv: Don't clobber r9 in relative_toc()
Date: Tue, 20 Sep 2011 13:44:51 +1000 [thread overview]
Message-ID: <1316490307-28030-4-git-send-email-benh@kernel.crashing.org> (raw)
In-Reply-To: <1316490307-28030-1-git-send-email-benh@kernel.crashing.org>
With OPAL, r8 and r9 will be used to pass the OPAL base and entry
for debugging purposes (those informations are also in the
device-tree). We don't want to clobber those registers that
early.
