Now that the enabled/disabled states for the preemption functions are declared alongside their definitions, the core PREEMPT_DYNAMIC logic is no longer tied to GENERIC_ENTRY, and can safely be selected so long as an architecture provides enabled/disabled states for irqentry_exit_cond_resched(). Make it possible to select HAVE_PREEMPT_DYNAMIC without GENERIC_ENTRY. For existing users of HAVE_PREEMPT_DYNAMIC there should be no functional change as a result of this patch.

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.
