Just one more quick note: - if you want to include the v2 changes in the commit message, then please describe them above your Signed-off-by (in the normal commit message body). - If you don't want the v2 notes to be present in the final commit message, then please add them between the "---" mark, and the diffstat.

[edk2-devel] [PATCH V2] UefiCpuPkg CpuCommFeaturesLib: Fix ASSERT if LMCE is supported
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1829 There will be ASSERT if LMCE is supported as below. DXE_ASSERT!: [CpuFeaturesDxe] XXX\UefiCpuPkg\Library\CpuCommonFeaturesLib\MachineCheck.c (342): ConfigData != ((void *) 0) The code should get Config Data and FeatureControlGetConfigData could be used. This issue is there since the code was added at the commit below. Revision: 3d6275c1137c9633ce24e31522b71105367bd6a0 Date: 2017/8/4 8:46:41 UefiCpuPkg CpuCommonFeaturesLib: Enable LMCE feature. The commits below are also related to move the code. Revision: 023387144299741d727521b425ef443438aecc1f Date: 2017/9/1 10:12:38 UefiCpuPkg/Lmce.c Remove useless file. Revision: 306a5bcc6b0170d28b0db10bd359817bb4b1db9f Date: 2017/8/17 11:40:38 UefiCpuPkg/CpuCommonFeaturesLib: Merge machine check code to same file. So, the code should not be tested at all on a platform that supports LMCE. BTW: A typo in LmceInitialize is also fixed. The typo is introduced by the commit below.
