doc: No longer allowed to use rcu_dereference on non-pointers
There are too many ways for the compiler to optimize (that is, break) dependencies carried via integer values, so it is now permissible to carry dependencies only via pointers. This commit catches up some of the documentation on this point. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

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.
