Well, it's a PITA because of #include dependencies in any case. Is

Hmm, where? page_address() already references ->virtual. I suppose 
CONFIG_SLUB_DEBUG is a no no as well then so do we want to add a 
CONFIG_KSIZE_DEBUG config option...? (Btw, I removed the BUG_ON() from 
kfree() as spotted by Vegard Nossum.)
