[PATCH 01/11] powerpc/64: irq_work avoid interrupt when called with hardware irqs enabled

irq_work_raise should not cause a decrementer exception unless it is called from NMI context. Doing so often just results in an immediate masked decrementer interrupt: <...>-55090d...4us : update_curr_rt <-dequeue_task_rt <...>-55090d...5us : dbs_update_util_handler
