#     powerpc/64s: Fix data interrupts vs d-side MCE reentrancy
#     
#     Handlers for interrupts that set DAR / DSISR, set MSR[RI] before those
#     SPRs are read and saved away.
#     
#     If a d-side machine check hits in this window, DAR / DSISR will be
#     clobbered silently, leading to random behaviour.
#     
#     Fix this by saving those registers before MSR[RI] is set.
