Subject: Re: [PATCH] x86: clean up confusing x86_mask

Hi Jia,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on v4.15-rc5]
[also build test ERROR on next-20171222]
[cannot apply to tip/x86/core]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
