level instruction. It is also an execution synchronizing instruction
except with respect to alterations to the POW and LE bits.
In addition, alterations to the MSR[EE] and MSR[RI] bits are
effective as soon as the instruction completes. Thus if MSR[EE]
= 0 and an external or decrementer exception is pending,
executing an mtmsr instruction that sets MSR[EE] = 1 will cause
the external or decrementer exception to be taken before the
next instruction is executed, if no higher priority exception exists.
