Subject: [PATCH 0/2] rcu: Extended quiescent state for adaptive nohz

From: Frederic Weisbecker <fweisbec@...il.com>

Paul, Ingo,

This is a rebase of the nohz cpusets RCU APIs on top of Paul's latest
-rcu (rcu/core) branch.

I have only built tested it yet, I need to do a full rebase of my
tree to test it in practice. But I wanted to show you how it looks
like first.

I also wonder if we can set that to a tree somewhere. Ingo suggested
to set up a tree on -tip to apply the uncontroversial part of nohz
cpusets patches and iterate from there. I think it would accelerate
everything if we start doing that.

Tell me what you think.

Thanks.

Frederic Weisbecker (2):
  rcu: New rcu_user_enter() and rcu_user_exit() APIs
  rcu: New rcu_user_enter_irq() and rcu_user_exit_irq() APIs
