[GIT PULL] printk: Support for full dynticks mode

[Frederic Weisbecker]

Ingo,

Please pull the support for full dynticks idle mode in printk that
can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	nohz/printk-v9

nohz/printk-v8 was the tree that I proposed to Linus. It has been left unpulled
though and we got no news from him but the tree has stayed untouched since then,
waiting in -next without any issue.

Part of nohz/printk-v8 is now in tip:irq/core, and this pull request contains
the rest. I could simply propose you the old branch but since there is a tiny
conflict with another recent commit in tip:irq/core, I just made a new branch
that contains tip:irq/core with nohz/printk-v8 merged inside which deals
with the conflict.

Thanks.
