[PATCH] hrtimers: cleanups and simplifications Clean up the interface to hrtimers by changing the init code to pass the mode as well as the clock. This allow the init code to select the correct base and eliminates extra timer re-init code in posix-timers. We also simplify the restart interface nanosleep use.

[PATCH] Export ktime_get_ts() This series removes the getnstimestamp() function from kernel/time.c in favor of kernel/hrtimer.c's ktime_get_ts() function which currently does exactly the same thing: retrieves a high-resolution (ns) timespec structure and performs the wall_to_monotonic adjustment. This patch: Export ktime_get_ts() to be used as a timestamp function since it uses getnstimefoday() and does the wall_to_monotonic adjustment.

[PATCH] hrtimers: optimize softirq runqueues The hrtimer softirq is called from the timer softirq every tick. Retrieve the current time from xtime and wall_to_monotonic instead of calling base->get_time() for each timer base. Store the time in the base structure and provide a hook once clock source abstractions are in place and to keep the code open for new base clocks.

[PATCH] fix next_timer_interrupt() for hrtimer Also from Thomas Gleixner <tglx@linutronix.de> Function next_timer_interrupt() got broken with a recent patch 6ba1b91213e81aa92b5cf7539f7d2a94ff54947c as sys_nanosleep() was moved to hrtimer. This broke things as next_timer_interrupt() did not check hrtimer tree for next event. Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ, VST) implementations, as the system can be in idle when next hrtimer event was supposed to happen. At least ARM and S390 currently use next_timer_interrupt().

[PATCH] Define __raw_get_cpu_var and use it There are several instances of per_cpu(foo, raw_smp_processor_id()), which is semantically equivalent to __get_cpu_var(foo) but without the warning that smp_processor_id() can give if CONFIG_DEBUG_PREEMPT is enabled. For those architectures with optimized per-cpu implementations, namely ia64, powerpc, s390, sparc64 and x86_64, per_cpu() turns into more and slower code than __get_cpu_var(), so it would be preferable to use __get_cpu_var on those platforms. This defines a __raw_get_cpu_var(x) macro which turns into per_cpu(x, raw_smp_processor_id()) on architectures that use the generic per-cpu implementation, and turns into __get_cpu_var(x) on the architectures that have an optimized per-cpu implementation.

[PATCH] hrtimer: create generic sleeper The removal of the data field in the hrtimer structure enforces the embedding of the timer into another data structure. nanosleep now uses a private implementation of the most common used timer callback function (simple task wakeup). In order to avoid the reimplentation of such functionality all over the place a generic hrtimer_sleeper functionality is created.

[PATCH] sched: cleanup, remove task_t, convert to struct task_struct cleanup: remove task_t and convert all the uses to struct task_struct. I introduced it for the scheduler anno and it was a mistake. Conversion was mostly scripted, the result was reviewed and all secondary whitespace and style impact (if any) was fixed up by hand.

[PATCH] posix-timers: Fix clock_nanosleep() doesn't return the remaining time in compatibility mode The clock_nanosleep() function does not return the time remaining when the sleep is interrupted by a signal. This patch creates a new call out, compat_clock_nanosleep_restart(), which handles returning the remaining time after a sleep is interrupted. This patch revives clock_nanosleep_restart(). It is now accessed via the new call out. The compat_clock_nanosleep_restart() is used for compatibility access. Since this is implemented in compatibility mode the normal path is virtually unaffected - no real performance impact.
