[PATCH v2 00/10] arm64: UEFI support

[Leif Lindholm]

This set adds support for UEFI to the arm64 port - a stub loader, as
well as runtime services support for efivars.

It depends on some core EFI patches currently in linux-next.

This includes bits shared between arm and arm64 support.
Remaining bits required for arm support will be submitted separately.

Changes from previous version:
- Reordered runtime and stub packages to avoid bisect breakage.
- Added more comments to efi-entry.S.
- Use actual instruction to generate "MZ" signature in head.S.
- Redundant cache/tlb maintenance removed.
- Properly use %pa instead of %llx in mm error messages..
- Stub deletes DT nodes of type "memory" instead of nodes called
  "memory".

Changes from earlier versions:
- Enter_virtual_mode() is now an early initcall.
- UEFI Reserved regions now preserved.
- Bugfix for dtb= support with SecureBoot.
- Stub now flushes instruction cache by address for kernel image area.
- CONFIG_EFI_STUB merged into CONFIG_EFI since they are interdependent.
- EFI_DEVICE_TREE_GUID renamed DEVICE_TREE_GUID.
- Minor cleanups.
