This allows for robust and correct behavior in cases of late or lost ticks, avoids interpolation errors, reduces duplication in arch specific code, and allows or assists future changes such as high-res timers, dynamic ticks, or realtime preemption. Additionally, it provides finer nanosecond resolution values to the clock_gettime functions. The patch set provides the minimal NTP changes, the clocksource abstraction, the core timekeeping code as well as the code to convert i386. I have started on converting more arches, but for now I'm only submmiting code for i386. As requested, I've reworked this patchset so it builds and boots every step of the way, resulting in one less patch in the patchset. This was done somewhat quickly and tested with my slow laptop, so it may be config dependent, but I think it should be ok. I've also tried to improve the patch descriptions as requested, but please let me know if they need more work. Changes since the last release: o Builds each step in the patchset o Improved patch descriptions o Reduced use of inline (might need more of this) o Simplified timespec_add_ns() o Removed unncessary additions (timer_pit sysfs bits) The patchset applies against the 2.6.15-rc5-git + the hrtimer patch-set already in -mm (same as the last release). It should replace the following patches currently in -mm: time-reduced-ntp-rework-part-1.patch time-reduced-ntp-rework-part-2.patch time-clocksource-infrastructure.patch time-generic-timekeeping-infrastructure.patch time-i386-conversion-part-1-move-timer_pitc-to-i8253c.patch time-i386-conversion-part-2-move-timer_tscc-to-tscc.patch time-i386-conversion-part-3-rework-tsc-support.patch time-i386-conversion-part-4-acpi-pm-variable-renaming-and-config-change.patch time-i386-conversion-part-5-enable-generic-timekeeping.patch time-i386-conversion-part-6-remove-old-code.patch time-i386-clocksource-drivers.patch Please note the slight re-ordering of the patches and that one patch has been removed from the set.
