Subject: [PATCH] powerpc: Add alignment handler for new lfiwzx instruction
Date: Fri, 20 Feb 2009 15:51:37 +1100 [thread overview]
Message-ID: <29888.1235105497@neuling.org> (raw)
lfiwzx is a new floating point load instruction in 2.06 that needs an
alignment handler for Linux.
Turns out to be the worlds easiest handler to add.
Signed-off-by: Michael Neuling <mikey@neuling.org>

Benh: this is for 2.6.30, but would be nice to be back in 2.6.27/28/29
too.
