  ef/libstub: arm/arm64: Randomize the base of the UEFI rt services region (2017-04-02 16:36:29 +0100)

----------------------------------------------------------------
EFI changes for v4.12:
- move BGRT handling to drivers/acpi so it can be shared between x86
  and ARM
- bring the EFI stub's initrd and FDT allocation logic in line with
  the latest changes to the arm64 boot protocol
- some changes to the EFI stub's command line parsing routines -- share
  more code, fix a minor buglet and add support for the 'quiet' command
  line parameter on ARM/arm64 (whose EFI stub is a bit noisy by default)
- randomize the virtual mapping of the UEFI runtime services on ARM/arm64
- other minor enhancements and fixes
