[edk2-devel] [Patch V4 00/15] Use CpuPageTableLib to create and update smm page table

[duntan]

In V4 patch set:
1.Add a new patch 'MdeModulePkg: Remove RO and NX protection when unset guard page'
2.Add a new patch 'UefiCpuPkg/PiSmmCpuDxeSmm: Clear CR0.WP before modify page table', the assumption that smm page table is always RW should be dropped.
3.Add DEBUG_CODE in 'UefiCpuPkg: Use CpuPageTableLib to convert SMM paging attribute.' to indicate that when mapping a range to present and EFI_MEMORY_RO or EFI_MEMORY_XP is not specificed, existing Present range in input range is set to NX disable and ReadOnly.
4.Sort mSmmCpuSmramRanges and mProtectionMemRange in seperate patches.
5.Seperate patches for creating smm runtime page table and smm s3 page table.
