Btw, I think this is a pretty important point. Linus suggested trying to
make slab initialization even earlier than what we now have. If we do
require GFP_BOOT annotations, then we'd need to sprinkle those all over
the place when we do that.

So from code shuffling point of view, it's better to support GFP_KERNEL
(almost) everywhere rather than require special annotations.
