Hi Cong,

I love your patch! Perhaps something to improve:

[auto build test WARNING on tip/sched/core]
[also build test WARNING on v4.17-rc3 next-20180430]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__
