powerpc/64s: Don't unbalance the return branch predictor in __replay_interrupt() The __replay_interrupt() code is branched to with bl, but the caller is returned to directly with rfid from the interrupt. Instead, rfid to a stub that returns to the caller with blr, which should keep the return branch predictor balanced. Reviewed-by: Gautham R.
