Because of a problem caused by a couple of commits in Josh Boyer's
tree, I have forced the master and powerpc-next branches back to where
they were until an hour or so ago.  Hopefully no-one has done a pull
in that time; if anyone has then they will need to do a git pull -f
when I eventually push the commits out (since they will have different
IDs).
