[PATCHv3 0/5] arm: arch_timer cleanups and niceties

[mark.rutland@arm.com (Mark Rutland)]

The following patches clean up some (harmless) fallout from the changes
in 3.9, and make the driver always use the virtual counter, eliminating
problems relating to choosing which counters to use (racy
initialisation, branches in hot paths).

The patches can also be found in my public git tree:
git://linux-arm.org/git/linux-mr.git clocks/arch-timer-cleanups

Russell, are you happy to take these for 3.11 if I send a pull request or drop
these in your patch system?

Since v1 [1]:
* Rebased to v3.10-rc1
* Fix up mach-shmobile's selection of ARCH_ARM_TIMER
Since v2: [2]:
* Added Simon Horman's ack for shmobile
* Clarified virtual timer CNTVOFF requirement per Christopher Covington's
  comments.

Thanks,
Mark.
