[edk2] [PATCH 0/6] Fix issues caused by NX memory protection
Posted by Jian J Wang 6 years, 11 months ago
NX memory protection feature enabled by PcdDxeNxMemoryProtectionPolicy
was not fully tested, especially if it's enabled for memory with type
of EfiBootServicesCode, EfiConventionalMemory and EfiReservedMemoryType.
This series will fix all issues caused by it.

Jian J Wang (6):
  UefiCpuPkg/MpInitLib: split wake up buffer into two parts
  UefiCpuPkg/CpuExceptionHandlerLib: alloc code memory for exception
    handlers
  UefiCpuPkg/CpuDxe: clear NX attr for page directory
  UefiCpuPkg/PiSmmCpuDxeSmm: Enable NXE if it's available
  MdeModulePkg/PiSmmCore: remove NX attr from SMM RAM
  MdeModulePkg/BootScriptExecutorDxe: remove NX attr for FfsBuffer
