      [PATCH] kill wall_jiffies · 8ef38609
      Atsushi Nemoto authored
      
      
      With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies.
      So we can kill wall_jiffies completely.
      
      This is just a cleanup and logically should not change any real behavior
      except for one thing: RTC updating code in (old) ppc and xtensa use a
      condition "jiffies - wall_jiffies == 1".  This condition is never met so I
      suppose it is just a bug.  I just remove that condition only instead of
      kill the whole "if" block.

      [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem) · 3171a030
      Atsushi Nemoto authored
      Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
      timer interrupt handler with this change.
      
      Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
      callers of do_timer() should know how many ticks to update.  Passing ticks
      get rid of this redundant calculation.  Also there are another redundancy
      pointed out by Martin Schwidefsky.
      
      This cleanup make a barrier added by
      5aee405c
      
       needless.  So this patch removes
      it.
      
      As a bonus, this cleanup make wall_jiffies can be removed easily, since now
      wall_jiffies is always synced with jiffies.  (This patch does not really
      remove wall_jiffies.  It would be another cleanup patch)
