2011-02-21timers: Export CLOCK_BOOTTIME via the posix timers interfaceJohn Stultz
This patch exports CLOCK_BOOTTIME through the posix timers interface CC: Jamie Lokier <jamie@shareable.org> CC: Thomas Gleixner <tglx@linutronix.de> CC: Alexander Shishkin <virtuoso@slind.org> CC: Arve Hjønnevåg <arve@android.com> Signed-off-by: John Stultz <john.stultz@linaro.org>
2011-02-21timers: Add CLOCK_BOOTTIME hrtimer baseJohn Stultz
CLOCK_MONOTONIC stops while the system is in suspend. This is because to applications system suspend is invisible. However, there is a growing set of applications that are wanting to be suspend-aware, but do not want to deal with the complications of CLOCK_REALTIME (which might jump around if settimeofday is called). For these applications, I propose a new clockid: CLOCK_BOOTTIME. CLOCK_BOOTTIME is idential to CLOCK_MONOTONIC, except it also includes any time spent in suspend. This patch add hrtimer base for CLOCK_BOOTTIME, using get_monotonic_boottime/ktime_get_boottime, to allow in kernel users to set timers against.

2011-02-21hrtimers: extend hrtimer base code to handle more then 2 clockidsJohn Stultz
The hrtimer code is written mainly with CLOCK_REALTIME and CLOCK_MONOTONIC in mind. These are clockids 0 and 1 resepctively. However, if we are to introduce any new hrtimer bases, using new clockids, we have to skip the cputimers (clockids 2,3) as well as other clockids that may not impelement timers. This patch adds a little bit of indirection between the clockid and the base, so that we can extend the base by one when we add a new clockid at number 7 or so.

2011-02-18ntp: Remove redundant and incorrect parameter checkRichard Cochran
The ADJ_SETOFFSET code redundantly checks the range of the nanoseconds field of the time value. This field is checked again in the subsequent call to timekeeping_inject_offset(). Also, as is, the check will not detect whether the number of microseconds is out of range. Let timekeeping_inject_offset() do the error checking.

2011-02-02posix clocks: Introduce dynamic clocksRichard Cochran
This patch adds support for adding and removing posix clocks. The clock lifetime cycle is patterned after usb devices. Each clock is represented by a standard character device. In addition, the driver may optionally implement custom character device operations. The posix clock and timer system calls listed below now work with dynamic posix clocks, as well as the traditional static clocks. The following system calls are affected: - clock_adjtime (brand new syscall) - clock_gettime - clock_getres - clock_settime - timer_create - timer_delete - timer_gettime - timer_settime [ tglx: Adapted to the posix-timer cleanup.
