Hi Ravi,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on tip/perf/core]
[also build test WARNING on v4.16 next-20180404]
[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__

Please review and possibly fold the followup patch.
