Hello, Ingo, and Happy New Year!
This pull request contains the following changes:
1. Updates to use cond_resched() instead of cond_resched_rcu_qs()
where feasible (currently everywhere except in kernel/rcu and
in kernel/torture.c). Also a couple of fixes to avoid sending
IPIs to offline CPUs.
http://lkml.kernel.org/r/20171201192122.GA19301@linux.vnet.ibm.com
2. Updates to simplify RCU's dyntick-idle handling.
http://lkml.kernel.org/r/20171201193625.GA20681@linux.vnet.ibm.com
3. Miscellaneous fixes.
http://lkml.kernel.org/r/20171201194139.GA22722@linux.vnet.ibm.com
4. Updates to remove almost all uses of smp_read_barrier_depends()
and read_barrier_depends().
http://lkml.kernel.org/r/20171201195053.GA23494@linux.vnet.ibm.com
5. Torture-test updates.
http://lkml.kernel.org/r/20171201200819.GA25519@linux.vnet.ibm.com
All of these changes have been subjected to 0day Test Robot and -next
testing, and are available in the git repository at:

Assuming that the subject line wanted to say v4.16, not v4.15 (which would be

You are correct, it is for the upcoming merge window, not for current
mainline.
Hmmm... Maybe this is why I have thus far succeeded in writing 2018
rather than 2017? ;-)
Thanx, Paul
