2011-02-02posix-timers: Introduce a syscall for clock tuning.Richard Cochran
A new syscall is introduced that allows tuning of a POSIX clock. The new call, clock_adjtime, takes two parameters, the clock ID and a pointer to a struct timex. Any ADJTIMEX(2) operation may be requested via this system call, but various POSIX clocks may or may not support tuning. [ tglx: Adapted to the posix-timer cleanup series. Avoid copy_to_user in the error case ] Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Acked-by: John Stultz <johnstul@us.ibm.com> LKML-Reference: <20110201134419.869804645@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-02-02ntp: Add ADJ_SETOFFSET mode bitRichard Cochran
This patch adds a new mode bit into the timex structure. When set, the bit instructs the kernel to add the given time value to the current time.

2011-02-02time: Introduce timekeeping_inject_offsetJohn Stultz
This adds a kernel-internal timekeeping interface to add or subtract a fixed amount from CLOCK_REALTIME. This makes it so kernel users or interfaces trying to do so do not have to read the time, then add an offset and then call settimeofday(), which adds some extra error in comparision to just simply adding the offset in the kernel timekeeping core.

2011-02-02posix-timers: Introduce clock_posix_cpuThomas Gleixner
The CLOCK_DISPATCH() macro is a horrible magic. We call common functions if a function pointer is not set. That's just backwards.
