vmap_area does not exist on no-MMU, therefore the GDB scripts fail to
load:
Traceback (most recent call last):
File "<...>/vmlinux-gdb.py", line 51, in <module>
import linux.vmalloc
File "<...>/scripts/gdb/linux/vmalloc.py", line 14, in <module>
vmap_area_ptr_type = vmap_area_type.get_type().pointer()
^^^^^^^^^^^^^^^^^^^^^^^^^
File "<...>/scripts/gdb/linux/utils.py", line 28, in get_type
self._type = gdb.lookup_type(self._name)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
gdb.error: No struct type named vmap_area.
To fix this, disable the command and add an informative error message if
CONFIG_MMU is not defined, following the example of lx-slabinfo.

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.
