Hi,

Changes since v1:

- Fixed preempt handling in alpha idle loop
- added ack from Geert
- fixed stable email address, sorry :-/

This time I built tested everywhere but: h8300 (compiler internal error),
and mn10300, parisc, score (cross compilers not available in
ftp://ftp.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/)

For testing, you can pull from:

git://github.com/fweisbec/linux-dynticks.git
	rcu/idle-fix-v2 

Thanks.
I have queued these on -rcu branch rcu/idle:

	git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git

This problem has been in place since 3.3, so it is hard to argue that
it is a regression for this merge window.  I have therefore queued it
for 3.7.
I don't follow that; I would expect any serious bug fix (serious enough
for a stable update) to be acceptable for 3.6 at this point.
OK, if any of the arch maintainers wishes to submit the patch to 3.6,
they are free to do so -- just let me know and I will drop the patch from
my tree.

That said, all this does is cause spurious warnings to be printed, so
not sure it really qualifies as serious.  But I am happy to leave that
decision with the individual arch maintainers -- it is their arch,
after all, so their decision.

							Thanx, Paul
If the regression occurred in 3.3, then the cc lines should be something
like:

    Cc: [off-list ref] # 3.3+

and not the current:

    Cc: 3.2.x.. [off-list ref]

(Note, version annotations should be on the right of the address, not in
the 'real name' position on the left.)
