Merge git://git.kernel.org/pub/scm/linux/kernel/git/tglx/linux-2.6-hrt
* git://git.kernel.org/pub/scm/linux/kernel/git/tglx/linux-2.6-hrt: clocksource: make clocksource watchdog cycle through online CPUs Documentation: move timer related documentation to a single place clockevents: optimise tick_nohz_stop_sched_tick() a bit locking: remove unused double_spin_lock() hrtimers: simplify lockdep handling timers: simplify lockdep handling posix-timers: fix shadowed variables timer_list: add annotations to workqueue.c hrtimer: use nanosleep specific restart_block fields hrtimer: add nanosleep specific restart_block member
