For noMMU system when you use larger rootfs image
there is problem with using _end label because
we increase klimit but in memory initialization
we use still _end which is wrong. Larger mtd rootfs
was rewritten by init_bootmem_node.
MMU kernel use static initialization where klimit
is setup to _end. There is no any other hanling
with klimit.

This patch fix problem with bad zone initialization.
This bug wasn't perform because Microblaze doesn't
define CONFIG_ZONE_DMA and ZONE_NORMAL was 0 for this case
that's why free_area_init works with correct values.
Original message:
I believe that the switch from ZONE_DMA (== 0) to ZONE_NORMAL
broke the free area initialization.

Some device drivers require the symbols _ebss, kernel_thread,
__page_offset or ___range_ok, so export them.
