Luke Browning 093c16bf9b [POWERPC] spufs: set SPU_CONTEXT_SWITCH_PENDING before synchronising SPU irqs ... synchronize_irq() provides the serialization for SPU_CONTEXT_SWITCH_PENDING which is read with a simple load. This routine guarantees that the relevant interrupt handlers are not running, so that the next time they do run they will see the update memory value. This must be done correctly so that exception handling code does not restart the mfc in the middle of a context switch while we are trying to atomically stop it and save state.
