There are still PS3-Linux users out there. They generally use firmware
and other tools available through the 'hacker' communities that allow
Linux to be run on more than just the 'officially supported' platforms.
Anyway, the change to use rcuwait seems fine if that's needed for the
completion re-work. I'll try to do some testing with the patch set
next week.
