  Modified files:
    sys/i386/i386        mem.c 
  Log:
  pmap_enter() masked off the page offset bits, pmap_kenter() did not.
  This (I believe) is the cause of the XFree86 startup and/or mptable(8)
  panics when programs were reading from /dev/mem at non-page-aligned
  offsets.  The offsets were being converted into random page flags in the
  page tables. :-(   (including PG_PS = 4MB page size)
