Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: hrtimers: fix warning in kernel/hrtimer.c x86: make sure we really have an hpet mapping before using it x86: enable HPET on Fujitsu u9200 linux/timex.h: cleanup for userspace posix-timers: simplify de_thread()->exit_itimers() path posix-timers: check ->it_signal instead of ->it_pid to validate the timer posix-timers: use "struct pid*" instead of "struct task_struct*" nohz: suppress needless timer reprogramming clocksource, acpi_pm.c: put acpi_pm_read_slow() under CONFIG_PCI nohz: no softirq pending warnings for offline cpus hrtimer: removing all ur callback modes, fix hrtimer: removing all ur callback modes, fix hotplug hrtimer: removing all ur callback modes x86: correct link to HPET timer specification rtc-cmos: export second NVRAM bank Fixed up conflicts in sound/drivers/pcsp/pcsp.c and sound/core/hrtimer.c manually.
