Peter Wemm 303f52d500 Merge rev 1.264 from i386/pmap.c (tegge via alfred):
Protect against an infinite loop when prefaulting pages.  This can
happen when the vm system maps past the end of an object or tries
to map a zero length object, the pmap layer misses the fact that
offsets wrap into negative numbers and we get stuck.
