Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Browse source 
Pull ARM updates from Russell King:

 - add support for ftrace-with-registers, which is needed for kgraft and
   other ftrace tools

 - support for mremap() for the sigpage/vDSO so that checkpoint/restore
   can work

 - add timestamps to each line of the register dump output

 - remove the unused KTHREAD_SIZE from nommu

 - align the ARM bitops APIs with the generic API (using unsigned long
   pointers rather than void pointers)

 - make the configuration of userspace Thumb support an expert option so
   that we can default it on, and avoid some hard to debug userspace
   crashes
