OK, I am not sure we actually need that. The thing is, no one is allowed
to use kmalloc() unless slab_is_available() returns true so we can just
grep for the latter and do something like the following patch. Does that
make powerpc boot nicely again? Ingo, I think this fixes the early irq
screams you were having too.
There's some more in s390 architecture code and some drivers (!) but I
left them out from this patch for now.
Pekka
