Greg Kroah-Hartman 0e75938323 nds32: fix up stack guard gap 
commit c453db6cd96418c79702eaf38259002755ab23ff upstream.

Commit 1be7107fbe ("mm: larger stack guard gap, between vmas") fixed
up all architectures to deal with the stack guard gap.  But when nds32
was added to the tree, it forgot to do the same thing.

Resolve this by properly fixing up the nsd32's version of
arch_get_unmapped_area()
