Full stress testing of 2.6.27-rc7 with the patch below threw up some
more places where we assume the mem_map is contigious:

	handle initialising compound pages at orders greater than MAX_ORDER

Following this email is an additional patch to fix up those places.
With this patch the libhugetlbfs functional tests pass, as do our stress
test loads.

Thanks to Jon Tollefson for his help testing these patches.

Please consider this patch for merge for 2.6.27.
