  Modified:    sys/i386/i386  pmap.c
               sys/i386/include  pmap.h
               sys/kern  kern_exec.c kern_exit.c subr_rlist.c
  Log:
  Performance optimizations.  One of which was meant to go in before the
  previous snap.  Specifically, kern_exit and kern_exec now makes a
  call into the pmap module to do a very fast removal of pages from the
  address space.  Additionally, the pmap module now updates the PG_MAPPED
  and PG_WRITABLE flags.  This is an optional optimization, but helpful
  on the X86.
