[PATCH v2 0/4] ArmPkg, ArmVirtPkg ARM: enable non-executable stack

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

This refactors the ARM version of CpuDxe and ArmMmuLib to align more closely
with the AARCH64 version, which primarily comes down to moving
ArmSetMemoryAttributes() to ArmMmuLib, where it can be used by non-DXE
modules such as DxeIpl. This is a PEI module which is in charge of
configuring the non-executable DXE stack.

Changes since v1:
- committed and dropped patch to fix RETURN_STATUS/EFI_STATUS disparities
  in function prototypes
- incorporated coding style feedback from Leif
- add R-b's from Leif and Laszlo

Ard Biesheuvel (4):
  ArmPkg: move ARM version of SetMemoryAttributes to ArmMmuLib
  ArmPkg/ArmMmuLib: remove VirtualMask arg from ArmSetMemoryAttributes
  ArmPkg/ArmMmuLib ARM: implement memory permission control routines
  ArmVirtPkg: enable non-executable DXE stack for all platforms
