For arch X64, system will enable the page table in SPI to cover 0-512G
range via CR4.PAE & MSR.LME & CR0.PG & CR3 setting. Existing code doesn't
cover the higher address access above 512G before memory-discovered
callback. This series patches provide the solution to enable paging from
temporary RAM Done.

Jiaxin Wu (5):
  UefiCpuPkg/SecCore: Migrate page table to permanent memory
  UefiCpuPkg/CpuMpPei: Conditionally enable PAE paging in 32bit mode
  MdeModulePkg/DxeIpl: Align Page table Level setting with previous
    level.
  OvmfPkg: Add CpuPageTableLib required by SecCore & CpuMpPei
  UefiPayloadPkg: Add CpuPageTableLib required by SecCore & CpuMpPei
