      x86/uv/time: Set ->min_delta_ticks and ->max_delta_ticks · 6fc46497
      Nicolai Stange authored
      In preparation for making the clockevents core NTP correction aware,
      all clockevent device drivers must set ->min_delta_ticks and
      ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
      clockevent device's rate is going to change dynamically and thus, the
      ratio of ns to ticks ceases to stay invariant.
      
      Currently, the x86's uv rtc clockevent device is initialized as follows:
      
        clock_event_device_uv.min_delta_ns = NSEC_PER_SEC /
                                       sn_rtc_cycles_per_second;
        clock_event_device_uv.max_delta_ns = clocksource_uv.mask *
                                       (NSEC_PER_SEC / sn_rtc_cycles_per_second);
      
      This translates to a ->min_delta_ticks value of 1 and a ->max_delta_ticks
      value of clocksource_uv.mask.
      
      Initialize ->min_delta_ticks and ->max_delta_ticks with these values
      respectively.
      
      This patch alone doesn't introduce any change in functionality as the
      clockevents core still looks exclusively at the (untouched) ->min_delta_ns
      and ->max_delta_ns. As soon as this has changed, a followup patch will
      purge the initialization of ->min_delta_ns and ->max_delta_ns from this
      driver.

      Currently, the tile's timer clockevent device is initialized as follows:
      
        evt->max_delta_ns = clockevent_delta2ns(MAX_TICK, evt);
      
      and
      
        .min_delta_ns = 1000,
      
      The first one translates to a ->max_delta_ticks value of MAX_TICK.
      For the latter, note that the clockevent core will superimpose a
      minimum of 1us by itself -- setting ->min_delta_ticks to 1 is safe here.
      
      Initialize ->min_delta_ticks and ->max_delta_ticks with these values.

      s390/time: Set ->min_delta_ticks and ->max_delta_ticks · 06c54611
      Nicolai Stange authored
      In preparation for making the clockevents core NTP correction aware,
      all clockevent device drivers must set ->min_delta_ticks and
      ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
      clockevent device's rate is going to change dynamically and thus, the
      ratio of ns to ticks ceases to stay invariant.
      
      Currently, the s390's CPU timer clockevent device is initialized as
      follows:
      
        cd->min_delta_ns    = 1;
        cd->max_delta_ns    = LONG_MAX;
      
      Note that the device's time to cycle conversion factor, i.e.
      cd->mult / (2^cd->shift), is approx. equal to 4.
      
      Hence, this would translate to
      
        cd->min_delta_ticks = 4;
        cd->max_delta_ticks = 4 * LONG_MAX;
      
      However, a minimum value of 1ns is in the range of noise anyway and the
      clockevent core will take care of this by increasing it to 1us or so.
      Furthermore, 4*LONG_MAX would overflow the unsigned long argument the
      clockevent devices gets programmed with.
      
      Thus, initialize ->min_delta_ticks with 1 and ->max_delta_ticks with
      ULONG_MAX.
      
      This patch alone doesn't introduce any change in functionality as the
      clockevents core still looks exclusively at the (untouched) ->min_delta_ns
      and ->max_delta_ns. As soon as this has changed, a followup patch will
      purge the initialization of ->min_delta_ns and ->max_delta_ns from this
      driver.

      clockevents/drivers/sh_cmt: Set ->min_delta_ticks and ->max_delta_ticks · bb2e94ac
      Nicolai Stange authored
      In preparation for making the clockevents core NTP correction aware,
      all clockevent device drivers must set ->min_delta_ticks and
      ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
      clockevent device's rate is going to change dynamically and thus, the
      ratio of ns to ticks ceases to stay invariant.
      
      Make the sh_cmt clockevent driver initialize these fields properly.
      
      This patch alone doesn't introduce any change in functionality as the
      clockevents core still looks exclusively at the (untouched) ->min_delta_ns
      and ->max_delta_ns. As soon as this has changed, a followup patch will
      purge the initialization of ->min_delta_ns and ->max_delta_ns from this
      driver.

      struct timespec is not y2038 safe on 32 bit machines.  Replace uses of
      struct timespec with struct timespec64 in the kernel.
      
      The syscall interfaces themselves will be changed in a separate series.
      
      Note that the restart_block parameter for nanosleep has also been left
      unchanged and will be part of syscall series noted above.
