Now that CONFIG_PREEMPT_DYNAMIC=y is the default, kernels that are ostensibly built with CONFIG_PREEMPT_NONE=y or CONFIG_PREEMPT_VOLUNTARY=y are now actually built with CONFIG_PREEMPT=y, but are by default booted so as to disable preemption. Although this allows much more flexibility from a single kernel binary, it means that the current rcutorture scenarios won't find build errors that happen only when preemption is fully disabled at build time. This commit therefore adds CONFIG_PREEMPT_DYNAMIC=n to several scenarios, and while in the area switches one from CONFIG_PREEMPT_NONE=y to CONFIG_PREEMPT_VOLUNTARY=y to add coverage of this Kconfig option.

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.
