commit6620999f0dupstream. 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.
