Make KVM guest pages be allocated dynamically and able to be swaped out.
One issue: all inodes returned from anon_inode_getfd are shared,
if one module changes field of the inode, other moduels might break.
Should we introduce a new API to not share inode?

You're not removing any shadows of the page, in case that page is a
guest page table. But I don't see anything wrong with it -- the page
won't change while it's in swap.
