Subject: [PATCH v2] powerpc/booke64: set RI in default MSR

From: Laurentiu Tudor <[email protected]>

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.

Applied to powerpc next, thanks.
