Subject: [PATCH 0/2] UefiCpuPkg/CpuMpPei X64: reallocate page tables in PEI

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3D4468=0D
=0D
Take a step towards enabling a generic approach to manage memory=0D
permissions in PEI, by wiring up the existing IA32 page table creation=0D
logic in CpuMpPei for X64 as well. This will enable future work to expose=0D
a PPI that is available throughout PEI to manage memory permissions in a=0D
generic manner across architectures.=0D
=0D
The DxeIpl that implements this logic today will be made redundant by=0D
this, and we should be able to retire it once the replacement pieces are=0D
all in place.=0D
