Broken LPAR cpu bringup

[Dave Hansen]

I'm just going to keep replying to myself.  It's fun.

I just noticed that, with your new patch, CPU0 also doesn't boot all the
way.  This happens about the time that init is exec'd off.  The CPU0
oops is garbled, so here is what I have.  I don't have any modules and
_end is at c00000000054b000, so it appears to have jumped off into lala
land.
