Patch Set 1:

Ugh... yeah, I didn't think about this part. My patch was pointless.

I'd really like to avoid pulling the `ro` struct out into a global... I think an alternative way to make this work is to check if mcache_size has been initialized directly (rather than checking cbmem_online()), and keep trying until we can. Can you check if CB:48482 works instead?
