Hello, Ingo,
This series contains the following changes:
1. Documentation updates, again just some simple changes.
Yes, I am getting behind on design-level updates. :-/
http://lkml.kernel.org/g/[email protected]
2. Expedited grace-period changes, most notably avoiding having
user threads drive expedited grace periods, using a workqueue
instead.
http://lkml.kernel.org/g/[email protected]
3. Miscellaneous fixes, including a performance fix for lists
that was sent with the lists modifications (second URL below).
I am holding the lists debug-enhancement modifications for the
next merge window, as there doesn't seem to be much energy
around providing fixes, and I cannot supply that energy for
this merge window. (I will make time as needed during the next
merge window.)

4. CPU hotplug updates, most notably providing exact CPU-online
tracking for RCU. This will in turn allow removal of the
checks supporting RCU's prior heuristic that was based on the
assumption that CPUs would take no longer than one jiffy to
come online.

5. Torture-test updates.

All of these changes have been subjected to 0day Test Robot and -next
testing, and are available in the git repository at:
