Merged as

     2  dcffad2491bc UefiCpuPkg/CpuPageTableLib: qualify page table accesses as volatile

via <https://github.com/tianocore/edk2/pull/5432>.

Unfortunately, the patch was formatted and/or posted incorrectly; git-am complained about "corrupt patch", no matter what I did about the quoted-printable encoding.

Therefore I had to manually reconstruct the patch (I noted that fact on the commit message).
