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
