https://lkml.org/lkml/2015/1/7/507.

3. Preemptible-RCU fixes, including fixing an old bug in the
interaction of RCU priority boosting and CPU hotplug. These were
posted to LKML at https://lkml.org/lkml/2015/1/7/535.

4. SRCU updates. These were posted to LKML at
https://lkml.org/lkml/2015/1/7/555.
