Subject: [PATCH] powerpc: Decode correct MSR bits in oops output

From: Anton Blanchard <[email-masked]>

On a 64bit book3s machine I have an oops from a system reset that
claims the book3e CE bit was set:

MSR: 8000000000021032 <ME,CE,IR,DR>  CR: 24004082  XER: 00000010

On a book3s machine system reset sets IBM bit 46 and 47 depending on
the power saving mode. Separate the definitions by type and for
completeness add the rest of the bits in.
