Currently, KASAN on LoongArch assume the CPU VA bits is 48, which is true for Loongson-3 series, but not for Loongson-2 series (only 40 or lower), this patch fix that issue and make KASAN usable for variable cpu_vabits. Solution is very simple: Just define XRANGE_SHADOW_SHIFT which means valid address length from VA_BITS to min(cpu_vabits, VA_BITS).

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.
