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

Pull late ARM updates from Russell King:
 "Here is the late set of ARM updates for this merge window; in here is:

   - The ARM parts of the broadcast timer support, core parts merged
     through tglx's tree.  This was left over from the previous merge to
     allow the dependency on tglx's tree to be resolved.

   - A fix to the VFP code which shows up on Raspberry Pi's, as well as
     fixing the fallout from a previous commit in this area.

   - A number of smaller fixes scattered throughout the ARM tree"
