Linus,

timers-urgent-for-linus
* Trivial fixes: Unused variable removal
* Posix-timers: Add the clock ID to the new proc interface to make it
useful. The interface is new and should be functional when we reach
the final 3.10 release.
* Cure a false positive warning in the tick code introduced by the
overhaul in 3.10
* Fix for a persistant clock detection regression introduced in this
cycle
Thanks,
tglx
