  SVN rev 183622 on 2008-10-05 09:56:14Z by kib
  MFC r183413:
  Frames created by the Xcpustop, Xrendezvous, Xipi_intr_bitmap_handler
  and Xlazypmap differ from the frame for Xtimerint. The Xtimerint puts
  pointer to the frame between return address and frame body, while rest
  of the functions listed above do not. Correct offset calculation to
  allow the ddb backtrace to step over such frames.
