[PATCH] fix remap_pte_range BUG

Out-of-tree user of remap_pfn_range hit kernel BUG at mm/memory.c:1112!
It passes an unrounded size to remap_pfn_range, which was okay before
2.6.12, but misses remap_pte_range's new end condition.  An audit of
all the other ptwalks confirms that this is the only one so exposed.
