The odds are that is from this loop:
for (i = 0; i < nr_pages; i++)
online_page(pfn_to_page(pfn + i));
So, either the pfn_to_page translation is bogus, or the pages aren't
mapped properly. I'd suspect the local_memmap patches. More complete
debugging info would include an 'addr2line -e c01669cf vmliunux' and
disassembly of online_page().
