Without a prototype, we'll have to add a prototype for each architecture implementing vDSO getrandom. As most architectures will likely have the vDSO getrandom implemented in a near future, and we'd like to keep the declarations compatible everywhere (to ease the libc implementor work), we should really just have one copy of the prototype. This also is what's already done inside of include/vdso/gettime.h for those vDSO functions, so this continues that convention.

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 reStructuredText 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.
