Subject: [PATCH] powerpc/powernv: Fix OPAL debug entry
Date: Mon, 22 Oct 2012 11:30:52 +1100 [thread overview]
Message-ID: <1350865852.2476.143.camel@pasglop> (raw)
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)
