I hit some rejects here due to Maynard Johnson and Bob Nelson's oprofile
patches.  It was relatively simple to fix up, but there may of course be
clashes in intent as well, so please check it all over carefully when it
lands in mainline.

I'll get all the ps3/spufs/etc stuff into Linus later today.


And what's up with all these powerpc people sending out patchbombs after
the merge window has opened?  Formally, _all_ of this:

should be pushed back into 2.6.24 because it all arrived too late.

I guess you're all doing that to Paul on a regular basis.  Bad.
