SubjectRe: [patch 1/2] x86,module: Detect VMX modules and disable Split-Lock-Detect
Hi Thomas,

I love your patch! Yet something to improve:

[auto build test ERROR on tip/auto-latest]
[also build test ERROR on next-20200403]
[cannot apply to jeyu/modules-next tip/x86/core v5.6]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
