Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King:
"The largest thing in this set of changes is bringing back some of the
ARMv3 code to fix a compile problem noticed on RiscPC, which we still
support, even though we only support ARMv4 there.
(The reason is that the system bus doesn't support ARMv4 half-word
accesses, so we need the ARMv3 library code for this platform.)
The rest are all quite minor fixes."
