Subject: [Patch v2 0/2] UefiCpuPkg/RegisterCpuFeaturesLib: Avoid AP calls PeiServices table.
Date: Mon, 15 Jul 2019 15:00:54 +0800	[thread overview]
Message-ID: <20190715070056.25916-1-eric.dong@intel.com> (raw)

V2 Changes:
1. Revert IsBitMaskMatchCheck change which is not correct.
2. refine some variable name.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1972

AP calls CollectProcessorData() to collect processor info.
CollectProcessorData function finally calls PcdGetSize function to
get DynamicPCD PcdCpuFeaturesSetting value. PcdGetSize will use gBS
which caused ASSERT. 
This patch serial fixes the issue and enhances the related code to avoid
later report this issue again.
