 Test case:
 
 #include <sys/mman.h>
 int main()
 {
         int i;
         mlock(&i, 4);
         return (0);
 }
 
 This appears to have been partially fixed by SVN r204160, but pmap_pte_release
 needs to be updated the same way as pmap_pte.  I'll commit this once I've had
 a chance to test further.
