The above data may be required for one function of makedumpfile (filter out kernel data) but not so crucial for makedumpfile as page descriptors and related data(e.g. pglist_data). Moreover, I'm preparing the release of v1.4.3 now, so I'll merge vmalloc support for PPC32 into v1.4.4. Is it all right for you, Suzuki ? Thanks Atsushi Kumagai
