Commit
7c5010c7f8 MdePkg/BaseLib.h: Update IA32_CR4 structure for 5-level paging
technically breaks the EDKII development process documented in
https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Development-Process
and Maintainers.txt in EDKII repo root directory.
The voilation is commit 7c5010c7f8 doesn't have a Reviewed-by or
Acked-by from MdePkg maintainers.
In order to revert 7c5010c7f8, 7365eb2c8 needs to revert first otherwise
simply reverting 7c5010c7f8 will cause build break.
