Pull RCU updates from Paul E. McKenney: "This series greatly reduces the performance degradation of Tree SRCU on a CPU-hotplug stress test. The effect was not subtle: Mike Galbraith measured Classic SRCU at 55 seconds and Tree SRCU at more than 16 -minutes- for this test. Mike collected ftrace data that showed that Classic SRCU was auto-expediting invocations of synchronize_srcu() that found SRCU completely idle. This series therefore adds this auto-expedite capability to Tree SRCU, bringing the performance shortfall to less than ten seconds, which is a great improvement over the initial shortfall of 15 minutes."

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
