Cover letter [patch 00/15] clocksource / timekeeping rework V4 (resend V3 + bug fix)
Greetings,
version 4 of the clocksource / timekeeping cleanup patches. If you wonder why version 3 did not show up on the mailing list: I had a hiccup with quilt which did strange things to the message ids and the post to lkml got rejected. Sorry for the spamming of the people on Cc.
John pointed out a subtle bug in v3 of the patch set with the reset of the cycle_last value in timekeeping_resume. Fixed in v4.
The latest additions are:
1) Change read_persistent_clock to return a struct timespec instead of an unsigned long with the number of seconds.
2) Introduce read_boot_clock to initialize wall_to_monotonic.
3) Move the reset of cycle_last to zero from the timekeeping code to the TSC code.
The patch set is based on todays upstream tree plus the patches from the tip tree, if anyone wants to try them you need to pull from the master branch of
git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-tip
Keeping the fingers crossed that this is now really done. John already gave his thumbs up for the patch series, so the next logical question is who is going to sit on the patches until the merge window is opened? I can certainly create a git branch on git390 for them, but the patches depend on some patches in the x86-tip tree. Thomas, any thoughts?
