Merge branch 'timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
hrtimers: Reorder clock bases
hrtimers: Avoid touching inactive timer bases
hrtimers: Make struct hrtimer_cpu_base layout less stupid
timerfd: Manage cancelable timers in timerfd
clockevents: Move C3 stop test outside lock
alarmtimer: Drop device refcount after rtc_open()
alarmtimer: Check return value of class_find_device()
timerfd: Allow timers to be cancelled when clock was set
hrtimers: Prepare for cancel on clock was set timers
