We encounter the following issue after commit 9cce9c6c2c3b ("arm64: mm: Handle
LVA support as a CPU feature").
(gdb) lx-slabinfo
Python Exception <class 'gdb.error'>: No symbol "vabits_actual" in current context.
Error occurred in Python: No symbol "vabits_actual" in current context.
We set vabits_actual based on TCR_EL1 value when
VA_BITS is bigger than 48.

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.
