scripts/gdb/vmalloc: disable on no-MMU
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.
