[PATCH] m32r: Fix build error of arch/m32r/mm/fault.c

The modification of "Changes for arch/m32r/mm/fault.c@1.3" was
prepared for enforce-a-gap-between-heap-and-stack.patch(*) of -mm tree,
but it has not been merged into mainline.
  (*) "heap-stack-gap for 2.6" (Sep. 25, 2004)
       http://www.uwsg.iu.edu/hypermail/linux/kernel/0409.3/0435.html

So, this patch is for withdrawing the previous arch/m32r/mm/fault.c.
