Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm

Pull ARM fixes from Russell King:
 "I've thought long and hard about what to say for this pull request,
  and I really can't work out anything sane to say to summarise much of
  these commits.  The problem is, for most of these are, yet again, lots
  of small bits scattered around the place without any real overall
  theme to them"

Most notable is probably the kuser page helper improvements.
