[edk2-devel] [PATCH 0/3] Fix potential issue in CpuPageTableLib and SMM page table initialization

["duntan" <dun.tan@intel.com>]

This patch set is to fix potential issue in CpuPageTableLib and SMM page table initialization

The first patch "UefiCpuPkg: Reduce and optimize access to attribute" is to reduce and optimize access to
attribute in page table modification code in CpuPageTableLib. 

The patch "UefiCpuPkg: Add more Paging mode enumeration" and " UefiCpuPkg/PiSmmCpuDxeSmm:Map SMRAM in 4K page granularity"
is to map SMRAM in 4K page granularity during SMM page table initialization(SmmInitPageTable).
This is to avoid the SMRAM paging-structure layout change(page split) when SMM ready to lock (PerformRemainingTasks).
