  ARM: add UEFI stub support (2015-12-14 10:38:21 +0100)

----------------------------------------------------------------
This implements UEFI kernel support for 32-bit ARM, based on the existing
arm64 support and existing generic early ioremap support. It is based on
commit f7d924894265 ("arm64/efi: refactor EFI init and runtime code for
reuse by 32-bit ARM"), which was pulled from the arm64 repo [1] as branch
'aarch64/efi'

[1] git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git

----------------------------------------------------------------
Ard Biesheuvel (12):
      mm/memblock: add MEMBLOCK_NOMAP attribute to memblock memory table
      arm64: only consider memblocks with NOMAP cleared for linear mapping
      arm64/efi: mark UEFI reserved regions as MEMBLOCK_NOMAP
      arm64/efi: split off EFI init and runtime code for reuse by 32-bit ARM
      arm64/efi: refactor EFI init and runtime code for reuse by 32-bit ARM
      ARM: add support for generic early_ioremap/early_memremap
      ARM: split off core mapping logic from create_mapping
      ARM: factor out allocation routine from __create_mapping()
      ARM: add support for non-global kernel mappings
      ARM: implement create_mapping_late() for EFI use
      ARM: only consider memblocks with NOMAP cleared for linear mapping
      ARM: wire up UEFI init and runtime support
