Remove the usage of the vvar _vdso_rng_data from the kernel-space code, as the x86 vvar machinery is about to be removed. The definition of the structure is unnecessary, as the data lives in a page pre-allocated by the linker anyways. The vdso user-space access to the rng data will be switched soon. DEFINE_VVAR_SINGLE() is now unused. It will be removed later togehter with the rest of vvar.h.

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.
