Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:

 - omit EFI memory map sorting, which was recently introduced, but
   caused problems with the decompressor due to additional sections
   being emitted.

 - avoid unaligned load fault-generating instructions in the
   decompressor by switching to a private unaligned implementation.

 - add a symbol into the decompressor to further debug non-boot
   situations (ld's documentation is extremely poor for how "." works,
   ld doesn't seem to follow its own documentation!)

 - parse endian information to sparse

* 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm:
  ARM: add debug ".edata_real" symbol
  ARM: 8716/1: pass endianness info to sparse
  efi/libstub: arm: omit sorting of the UEFI memory map
  ARM: 8715/1: add a private asm/unaligned.h
