Based on some profiles we noticed the first vmalloc region was being
continually cast out and replaced.  All modules end up there so it is one
of our hottest segments.

This patch bolts the vmalloc region into the second segment.  SLB misses on
an NFS benchmark were reduced by about 10% with this patch.
