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
