  Modified files:
    sys/i386/i386        mem.c 
  Log:
  Take a shot at fixing a nasty bug in the pmap changes that I did.  I
  missed the pmap_kenter/kremove in this file, which leads to read()/write()
  of /dev/mem using stale TLB entries. (gah!)  Fortunately, mmap of /dev/mem
  wasn't affected, so it wasn't as bad as it could have been.  This throws
  some light on the 'X server affects stability' thread....
