Björn Töpel c817dcb2a6 bpf, x86: Fix "no previous prototype" warning 
commit f45b2974cc upstream.

The arch_prepare_bpf_dispatcher function does not have a prototype, and
yields the following warning when W=1 is enabled for the kernel build.

  >> arch/x86/net/bpf_jit_comp.c:2188:5: warning: no previous \
  prototype for 'arch_prepare_bpf_dispatcher' [-Wmissing-prototypes]
        2188 | int arch_prepare_bpf_dispatcher(void *image, s64 *funcs, \
	int num_funcs)
             |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Remove the warning by adding a function declaration to include/linux/bpf.h.

README 

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.
