Add support for SRCU. Herd creates srcu events and linux-kernel.def associates them with three possible annotations (srcu-lock, srcu-unlock, and sync-srcu) corresponding to the API routines srcu_read_lock(), srcu_read_unlock(), and synchronize_srcu(). The linux-kernel.bell file now declares the annotations and determines matching lock/unlock pairs delimiting SRCU read-side critical sections, and it also checks for synchronize_srcu() calls inside an RCU critical section (which would generate a "sleeping in atomic context" error in real kernel code). The linux-kernel.cat file now adds SRCU-induced ordering, analogous to the existing RCU-induced ordering, to the gp and rcu-fence relations. Curiously enough, these small changes to the model's .cat code are all that is needed to describe SRCU. Portions of this patch (linux-kernel.def and the first hunk in linux-kernel.bell) were written by Luc Maranget.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
