Subject[GIT PULL] printk: Support for full dynticks mode

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


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.


Frederic Weisbecker (5):
nohz: Add API to check tick state
irq_work: Don't stop the tick with pending works
irq_work: Make self-IPIs optable
printk: Wake up klogd using irq_work
Merge branch 'nohz/printk-v8' into irq/core

Steven Rostedt (2):
irq_work: Flush work on CPU_DYING
irq_work: Warn if there's still work on cpu_down
