[PATCH 0/4] AARCH64: enable stack alignment check

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

This series enables the stack alignment check (SA) bit in the MMU for
AArch64 platforms, as mandated by the UEFI spec. No fixes were required
to make the existing asm code adhere to this requirement, but some issues
were spotted in review nonetheless, so these are fixed as well.

Ard Biesheuvel (4):
  ArmPlatformPkg/ArmPlatformStackLib: use callee preserved registers
  ArmPkg/ArmLib: AARCH64: set frame pointer in cache maintenance routine
  ArmPkg/ArmLib: AARCH64: allow the stack aligment (SA) bit to be
    managed
  ArmPkg/ArmMmuLib: AARCH64: enable stack alignment checking
