Subject: [patch 0/2] nohz tweaking

Greetings,
the two remainting patches of the nohz performance work I've been
doing. Both have been sent to the mailing lists before. Ingo had
a comment about patch #1, but no one but me seems to be interested
in patch #2. Neverless I would like to get both patches upstream.
I can create a branch for them on git390 but I feel that they should
go the path all the other nohz/time/clocksource patches went.

Sorry, that's my fault. I forgot them over the watchdog
wreckage. Picking them up now.

Thanks,

Thats great, thanks. And yes the clocksource/watchdog problems have
been painful..

I could not find the patches on tip timers/core. Where did you put them ?

eed3b9c: nohz: Reuse ktime in sub-functions of tick_check_idle.
7bc7d63: time: Remove xtime_cache
a092ff0: time: Implement logarithmic time accumulation

Thanks for the list. Thomas added 3c5d92a and eed3b9c yesterday and
I am happy now. I have two more optimization patches for the clockevents
code, but I'm not don't quite content with them yet.
