This is silly. We modify totalram_pages as we balloon up and down, so this
really isn't very max_pfn-like after ballooning gets under way.
So I've applied the patch but I made it a no-op if !defined(CONFIG_XEN),
until/unless someone comes up with a better alternative to totalram_pages.
Possibly just latching totalram_pages when we install the balloon driver
would be sufficient?
