parisc: fix kernel BUG at arch/parisc/include/asm/mmzone.h:50 (part 2)
Make sure that we really return -1 (instead of 0x00ff) as node id for page frame numbers which are not physically available. This finally fixes the kernel panic when running cat /proc/kpageflags /proc/kpagecount. Theoretically this patch now limits the number of physical memory ranges to 127 instead of 254, but currently we have MAX_PHYSMEM_RANGES hardcoded to 8 which is sufficient for all existing parisc machines.
