Subject: [PATCH 4.4 266/266] powerpc/booke64: set RI in default MSR

From: Laurentiu Tudor <laurentiu.tudor@....com>

commit 5266e58d6cd90ac85c187d673093ad9cb649e16d upstream.

Set RI in the default kernel's MSR so that the architected way of
detecting unrecoverable machine check interrupts has a chance to work.
This is inline with the MSR setup of the rest of booke powerpc
architectures configured here.
