Those same 4 builds had CONFIG_SPARSEMEM=y. It may be a coincidence -- I haven't found out yet. One of the 4 randconfig files is attached. Here is a sampling of build errors: ../include/linux/mm.h: In function ‘is_pinnable_page’: ../include/asm-generic/memory_model.h:64:14: error: implicit declaration of function ‘page_to_section’; did you mean ‘__nr_to_section’?
