2013-04-05timekeeping: Store cycle_last value in timekeeper struct as wellThomas Gleixner1-0/+2
For implementing a shadow timekeeper and a split calculation/update region we need to store the cycle_last value in the timekeeper and update the value in the clocksource struct only in the update region. Add the extra storage to the timekeeper. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: John Stultz <john.stultz@linaro.org>
2013-03-23timekeeping: Move lock out of timekeeper structThomas Gleixner1-2/+0
Make the lock a separate entity. Preparatory patch for shadow timekeeper structure. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> [Merged with CLOCK_TAI changes] Signed-off-by: John Stultz <john.stultz@linaro.org>
2013-03-23hrtimer: Add hrtimer support for CLOCK_TAIJohn Stultz1-0/+2
Add hrtimer support for CLOCK_TAI, as well as posix timer interfaces. Signed-off-by: John Stultz <john.stultz@linaro.org>
2013-03-23timekeeping: Move TAI managment into timekeeping core from ntpJohn Stultz1-0/+3
Currently NTP manages the TAI offset. Since there's plans for a CLOCK_TAI clockid, push the TAI management into the timekeeping core.

2012-09-24time: Introduce new GENERIC_TIME_VSYSCALLJohn Stultz1-7/+29
Now that we moved everyone over to GENERIC_TIME_VSYSCALL_OLD, introduce the new declaration and config option for the new update_vsyscall method.

2012-09-24time: Convert CONFIG_GENERIC_TIME_VSYSCALL to CONFIG_GENERIC_TIME_VSYSCALL_OLDJohn Stultz1-3/+4
To help migrate archtectures over to the new update_vsyscall method, redfine CONFIG_GENERIC_TIME_VSYSCALL as CONFIG_GENERIC_TIME_VSYSCALL_OLD Cc: Tony Luck <tony.luck@intel.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Paul Turner <pjt@google.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Richard Cochran <richardcochran@gmail.com> Cc: Prarit Bhargava <prarit@redhat.com> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: John Stultz <john.stultz@linaro.org>
2012-09-24time: Move update_vsyscall definitions to timekeeper_internal.hJohn Stultz1-0/+17
Since users will need to include timekeeper_internal.h, move update_vsyscall definitions to timekeeper_internal.h.

2012-09-24time: Move timekeeper structure to timekeeper_internal.h for vsyscall changesJohn Stultz1-0/+68
We're going to need to access the timekeeper in update_vsyscall, so make the structure available for those who need it.
