This series is aimed at offering the minimum level of support that KVM
needs when it comes to architected timers.

The first patch changes the driver to use the virtual timer by default
instead of the physical one (access to the later is conditioned by the
hypervisor settings, while the former is always available). This could
be required even if the kernel is not running as a guest.

The second patch exposes a clockcycle counter that can be used by
other subsystems.

Patches based on v3.6-rc1.
