      x86: Fix vrtc_get_time/set_mmss to use new timespec interface · ce0b0989
      John Stultz authored
      The patch "x86: Increase precision of x86_platform.get/set_wallclock"
      changed the x86 platform set_wallclock/get_wallclock interfaces to
      use nsec granular timespecs instead of a second granular interface.
      
      However, that patch missed converting the vrtc code, so this patch
      converts those functions to use timespecs.
      
      Many thanks to the kbuild test robot for finding this!

      power: Add option to log time spent in suspend · 5c83545f
      Colin Cross authored
      Below is a patch from android kernel that maintains a histogram of
      suspend times. Please review and provide feedback.
      
      Statistices on the time spent in suspend are kept in
      /sys/kernel/debug/sleep_time.

      [zoran.markovic@linaro.org: Re-formatted suspend time table to better
      fit expected values. Moved accounting of suspend time into timekeeping
      core. Removed CONFIG_SUSPEND_TIME flag and made the feature conditional
      on CONFIG_DEBUG_FS. Changed the file name to sleep_time to better fit
      terminology in timekeeping core. Changed seq_printf to seq_puts. Tweaked

      alarmtimer: Add functions for timerfd support · 6cffe00f
      Todd Poynor authored
      Add functions needed for hooking up alarmtimer to timerfd:
      
      * alarm_restart: Similar to hrtimer_restart, restart an alarmtimer after
        the expires time has already been updated (as with alarm_forward).
      
      * alarm_forward_now: Similar to hrtimer_forward_now, move the expires
        time forward to an interval from the current time of the associated clock.
      
      * alarm_start_relative: Start an alarmtimer with an expires time relative to
        the current time of the associated clock.
      
      * alarm_expires_remaining: Similar to hrtimer_expires_remaining, return the
        amount of time remaining until alarm expiry.
