I still think that there are major changes that should be done to the
Microblaze ABI. I actually did most of the work for this, but then you
beat be by getting it upstream first ;-)

I suppose it's much too late for 2.6.30 now, but maybe we can do one major

merge window. I'll follow up with an RFC for this.
