[PATCH v2 00/14] UEFI support for arm(64)

[Leif Lindholm]

Since all prerequisites are not ready for the (32-bit) arm patches to
go in, I have broken these out of this set and will be resubmitting
them separately.

This set now provides arm64 support only - but includes the code that
is common between the ARM ports.

Prerequisites for this set are:
- Mark Salter's generic early_ioremap()
- Matt Fleming's efi_enabled() rework

Changes from the last upstream posting:
- Some cleanup based on feedback
- Fixed range test in create_id_mapping()
- Fixed name of guard ifdef in arch/arm64/include/asm/efi.h
- Fixed memory corruption bug caused by late use of
  create_id_mapping(). That function uses memblock_alloc()
  to allocate new pmd/pte pages and it was being called
  after slab allocator was initialized. This led to
  possibility that the allocated memory for pmd/pte was
  already in use by something else. Now, create_id_mapping()
  gets called just after paging_init() when it is still okay
  to use memblock_alloc().
- Fixed whitespace error in efi-entry.S
- Now support 64K pagesize in EFI runtime
- Undid the breakage I caused to Ard's dtb= SecureBoot patch
