Subject: [PATCH] powerpc/powernv: Fix OPAL debug entry

From: Benjamin Herrenschmidt <[email-masked]>
Date: Mon, 22 Oct 2012 11:30:52 +1100

OPAL provides the firmware base/entry in registers at boot time
for debugging purposes. We had a bug in the code trying to stash
these into the appropriate kernel globals (a line of code was
probably dropped by accident back when this was merged)
