Arnd Bergmann fae9ca7915 [POWERPC] spufs: synchronize IRQ when disabling ... There is a small race between the context save procedure and the SPU interrupt handling, where we expect all interrupt processing to have finished after disabling them, while an interrupt is still being processed on another CPU. The obvious fix is to call synchronize_irq() after disabling the interrupts at the start of the context save procedure to make sure we never access the SPU any more during an ongoing save or even after that. Thanks to Benjamin Herrenschmidt for pointing this out.
