Pull ARM updates (part one) from Russell King:

 - MMC patches from Ulf Hansson and Pawel Moll.  These add support for
   DDR mode and the latest variant found on ARM Versatile Express, as
   well as a number of cleanups.

 - A fix for to improve the behaviour of ARMs sched_clock()

 - Changes to the ARM ioremap() code.  I'm not convinced with the
   primary arguments for this, but it's been around for a while, and
   people seem happy with it - and the "other" justification for this is
   at

      http://lkml.org/lkml/2012/12/6/184

 - Add SCHED_HRTICK to ARMs Kconfig

 - Making the ARM SHA/AES code Thumb-2 compatible

 - A collection of other small updates.
