Yoichi, please correct me if I am wrong but I think that the "standby"
instruction does not set IE bit on its own, so calling it with
interrupts disabled will loop the cpu away forever on standby state
being unable to come back due to no interrupts getting through.
Please ack the patch if you consider it correct.
Please apply afterwards, Ralf.
Standby instruction can't be called with interrupts disabled
as it doesn't set IE bit on it's own.
