Currently, we only support 52-bit virtual addressing on 64k pages configurations, and in all other cases, vabits_actual is guaranteed to equal VA_BITS (== VA_BITS_MIN). So get rid of the variable entirely in that case. While at it, move the assignment out of the asm entry code - it has no need to be there.

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.
