      [PATCH] Add getnstimestamp function · 64123fd4
      Matt Helsley authored
      There are several functions that might seem appropriate for a timestamp:
      
      get_cycles()
      current_kernel_time()
      do_gettimeofday()
      <read jiffies/jiffies_64>
      
      Each has problems with combinations of SMP-safety, low resolution, and
      monotonicity. This patch adds a new function that returns a monotonic SMP-safe
      timestamp with nanosecond resolution where available.
      
      Changes:
      	Split timestamp into separate patch
      	Moved to kernel/time.c
      	Renamed to getnstimestamp
      	Fixed unintended-pointer-arithmetic bug

      [PATCH] NTP shift_right cleanup · 1bb34a41
      john stultz authored
      Create a macro shift_right() that avoids the numerous ugly conditionals in the
      NTP code that look like:
      
              if(a < 0)
                      b = -(-a >> shift);
              else
                      b = a >> shift;
      
      Replacing it with:
      
              b = shift_right(a, shift);
      
      This should have zero effect on the logic, however it should probably have
      a bit of testing just to be sure.
      
      Also replace open-coded min/max with the macros.

      [PATCH] time interpolator: Fix settimeofday inaccuracy · 9acf6597
      Christoph Lameter authored
      settimeofday will set the time a little bit too early on systems using
      time interpolation since it subtracts the current interpolator offset
      from the time. This used to be necessary with the code in 2.6.9 and earlier
      but the new code resets the time interpolator after setting the time.
      Thus the time is set too early and gettimeofday will return a time slightly
      before the time specified with settimeofday if invoked immeditely after
      settimeofday.
      
      This removes the obsolete subtraction of the time interpolator offset
      and makes settimeofday set the time accurately.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
