Does kernel include memory management?
I'd guess it does, as the R5 kernel did, and there are vm/ and vm2/ directories in the kernel source
Sure it does, but it's not yet in its final state. The current VM written by Travis is under vm/, and Michael wrote one which is not yet integrated or completed in vm2/.
I don't know yet where we end up with those, though, probably it's going to be a mix between the two.
