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.
