Hello, Ingo,
Could you please pull one more commit? This is an update to Frederic
Weisbecker's context-tracking subsystem that is another stepping stone
towards adaptive-idle and tickless userspace execution. This has been
subjected to -next testing. It does give two checkpatch.pl errors,
but these are on cpp macro definitions used within assembly code -- and
following checkpatch.pl's suggestions would result in assembler errors.
(I have reported this to Andy Whitcroft, checkpatch.pl's maintainer.)
These changes are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/next
Thanx, Paul

Pulled it and pushed it out earlier this week.
One issue I wanted to raise on a bit wider forum was the
introduction of the (small) kernel/context_tracking.c subsystem.
It makes sense to me, but I've Cc:-ed Linus and Andrew, in case
they have a different opinion.
Thanks,
Ingo

And it does appear that Frederic and I have a bit more explaining to do. ;-)
Thanx, Paul

Right :-)
Andrew strongly suggested us to give some more description of that
thing and the role and semantics of the new APIs. I indeed overlooked
that part. I'll send a patch soon.
