ksm: fix m68k build: only NUMA needs pfn_to_nid
A CONFIG_DISCONTIGMEM=y m68k config gave mm/ksm.c: In function `get_kpfn_nid': mm/ksm.c:492: error: implicit declaration of function `pfn_to_nid' linux/mmzone.h declares it for CONFIG_SPARSEMEM and CONFIG_FLATMEM, but expects the arch's asm/mmzone.h to declare it for CONFIG_DISCONTIGMEM (see arch/mips/include/asm/mmzone.h for example). Or perhaps it is only expected when CONFIG_NUMA=y: too much of a maze, and m68k got away without it so far, so fix the build in mm/ksm.c.
