I went to go attempt this, but ia64 is still a holdout, as its
DISCONTIGMEM setup can't use the generic memory_model definitions.
#ifdef CONFIG_DISCONTIGMEM
# define page_to_pfn(page) ((unsigned long) (page - vmem_map))
# define pfn_to_page(pfn) (vmem_map + (pfn))
#else
# include <asm-generic/memory_model.h>
#endif
#else
# include <asm-generic/memory_model.h>
#endif
