seems there was a merge error here when adding the patch to the stable
branch.  this change disables a large number of things when it should
only be disabling mmap_min_addr.  notice how the first #ifdef appears
at line ~1200 while the second appears at line ~1353.  the original
commit was ~1214 to ~1221.
