The purpose of this patch series is to put the AP in 64-bit mode before handing off the boot process to the OS. To do this, duplicate relocateApLoop for processors with SEV-ES, allocate contiguous memory, then create page tables and keep AP in 64-bit mode.
Yuanhao Xie (5): UefiCpuPkg: Duplicate RelocateApLoop for the processors with SEV-ES. UefiCpuPkg: Contiguous memory allocation and code clean-up. OvmfPkg: Add CpuPageTableLib required by MpInitLib. UefiPayloadPkg: Add CpuPageTableLib required by MpInitLib. UefiCpuPkg: Put APs in 64 bit mode before handoff to OS.
