Pull RCU updates from Paul E. McKenney:
" 1. Update RCU documentation. These were posted to LKML at
https://lkml.org/lkml/2014/4/28/634.
2. Miscellaneous fixes. These were posted to LKML at
https://lkml.org/lkml/2014/4/28/645.
3. Torture-test changes. These were posted to LKML at
https://lkml.org/lkml/2014/4/28/667.
4. Variable-name renaming cleanup, sent separately due to conflicts.
This was posted to LKML at https://lkml.org/lkml/2014/5/13/854.
5. Patch to suppress RCU stall warnings while sysrq requests are
being processed. This patch is the RCU portions of the patch
that Rik posted to LKML at https://lkml.org/lkml/2014/4/29/457.
The reason for pushing this patch ahead instead of waiting until
3.17 is that the NMI-based stack traces are messing up sysrq
output, and in some cases also messing up the system as well."
