        arch/mips/kernel: irq_cpu.c 

Log message:
        Use an irq_enable_hazard hazard barrier in unmask_mips_irq.  This
        hasn't been an actual bug, so it's more a change to be 100% compliant
        with the requirements of the architecture spec.  Similar fix to
        mask_mips_irq where there was a slightly less theoretical chance of
        getting hit.
