Jason Wang points out that it's vary hard for users to build an array of stat names. The naive thing is to use VIRTIO_BALLOON_S_NR but that breaks if we add more stats. Let's add an array of reasonably readable names.

Here is a set of small patches that enables hugetlb on PV machines. They are against xen-unstable and linux-2.6.18-xen. The patches are specifically for x86_64. I originally had these patches working back in May, but recently for some reason my machine now refuses to boot the baseline xen-unstable, so I''ve been unable to verify them....

I don't. The list of 'if's is better than the indirect function call. That's terribly expensive, and the way we reuse the lru.next field is fragile.

Has anyone tried getting wine to use HugeTLB yet? I see a real need for this for games.
