mbm_locat_bytes_config -> mbm_local_bytes_config

Should this be "directories"?

Based on the hierarchy presented the files mentioned here may be expected
to be associated with RFTYPE_CTRL_INFO | RFTYPE_RES_CACHE.
For accuracy it may be better to move num_closids one level higher so
that it is only associated with RFTYPE_CTRL_INFO?

directories?

Please remove space before tab for a clean checkpatch.pl run.

Since "base" refers to more than the root directory I think this can
just be "base directory structure".
