Here's a last minue pull request before today's soft freeze.  Ideally
 I would have sent this earlier, but I was waiting for a couple of
 extra fixes I knew were close.  And the freeze crept up on me, like
 always.
 
 Most of the changes here are bugfixes in any case.  There are some
 cleanups as well, which have been in my staging tree for a little
 while.  There are a couple of truly new features (some extensions to
 the sam460ex platform), but these are low risk, since they only affect
 a new and not really stabilized machine type anyway.
 
 Higlights are:
   * Mac platform improvements from Mark Cave-Ayland
   * Sam460ex improvements from BALATON Zoltan et al.
   * XICS interrupt handler cleanups from Cédric Le Goater
   * TCG improvements for atomic loads and stores from Richard
     Henderson
   * Assorted other bugfixes
