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

Pull ARM fixes from Russell King:
 "A number of ARM updates for -rc, covering mostly ARM specific code,
  but with one change to modpost.c to allow Thumb section mismatches to
  be detected.

  ARM changes include reporting when an attempt is made to boot a LPAE
  kernel on hardware which does not support LPAE, rather than just being
  silent about it.

  A number of other minor fixes are included too"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 7992/1: boot: compressed: ignore bswapsdi2.S
  ARM: 7991/1: sa1100: fix compile problem on Collie
  ARM: fix noMMU kallsyms symbol filtering
  ARM: 7980/1: kernel: improve error message when LPAE config doesn't match CPU
  ARM: 7964/1: Detect section mismatches in thumb relocations
  ARM: 7963/1: mm: report both sections from PMD
