Ingo, Thomas,
Please pull the timers/cputime-fix-steal-v2 branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
timers/cputime-fix-steal-v2
It's based on tip:timers/core. The patches are essentially unchanged
since the last version (https://lkml.org/lkml/2014/3/6/376). I only
added a small comment in 4/6 and acks from Rik.
---
The main purpose of this set is to fix a bug on full dynticks configs
where steal time accounting appears to be zero in /proc/stat even
after a few seconds of competing guests running busy loops in a same
host CPU. It's not a regression though as it was there since the
beginning with full dynticks.
So patch [4/6] ("cputime: Fix jiffies based cputime assumption on
steal accounting") is the most important patch of the series. The rest
is mostly preparatory work to fix the bug plus various cleanups.
Thanks,
Frederic

Many architectures have a stub cputime.h that only include the default
cputime.h
Lets remove the useless headers, we only need to mention that we want
the default headers on the Kbuild files.

That's a double fail there, not sorted and no EOL.
Please run the script from commit: b119fa61d440f after you touch the
asm/Kbuild files.

I don't see why we need to sort them. But I'm running the script anyway.
Will resend, thanks.

sfr gets real grumpy if we don't, at one point I gave in and wrote that
script, because I sure as hell wasn't going to manually sort all those
files every time I did a automated addition.

I see, it's to avoid merge conflicts then. Granted.

Many architectures have a stub cputime.h that only include the default
cputime.h
Lets remove the useless headers, we only need to mention that we want
the default headers on the Kbuild files.
While at it, resort alphabetically the entries in arch/*/include/asm/Kbuild
for those that have been touched. For this we use the script in commit
b119fa61d440f as suggested by Peter Zijlstra.

Hi,
The main purpose of this set is to fix a bug on full dynticks configs
where steal time accounting appears to be zero in /proc/stat even
after a few seconds of competing guests running busy loops in a same
host CPU. It's not a regression though as it was there since the
beginning with full dynticks.
So patch [4/6] is the most important. The rest is preparatory work
to fix the bug and various cleanups.
Thanks.

Many architectures have a stub cputime.h that only include the default
cputime.h
Lets remove the useless headers, we only need to mention that we want
the default headers on the Kbuild files.
