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.
