  Modified files:
    sys/ia64/ia64        machdep.c 
  Log:
  Use pmap_steal_memory() for the msgbuf instead of trying to squeeze
  it in the last chunk (phys_avail block). The last chunk very often is
  not larger than one or two pages, resulting in a msgbuf that's too
  small to hold a complete verbose boot.
  Note that pmap_steal_memory() will bzero the memory it "allocates".
  Consequently, ia64 will never preserve previous msgbufs. This is not
  a noticable difference in practice. If the msgbuf could be reused,
  it was invariably too small to have anything preserved anyway.
