This patch remove bug which I reported but there is another place which
needs to be changed.
I am not sure if my patch is correct but at least point you on places
which is causing compilation errors.
I tested your memblock branch with this fix and microblaze can boot.
Ok, that's missing in my initial rename patch. I'll fix it up. Thanks.
Cheers,
Ben.
I don't know why but this unfixed old patch is in linux-next today. Not
sure which tree contains it.
Thanks,
Michal
