The paravirt MMU functions called via the PV_CALLEE_SAVE_REGS_THUNK() macro can't be defined to be static, as the macro is generating a function via asm() statement calling the paravirt MMU function. In order to avoid warnings when specifying "-Wmissing-prototypes" for the build, add local prototypes (there should never be any external caller of those functions).

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.
