Leaving 256K pages aside for now, do you plan to revise the 4/16/64K page size patch for 2.6.29? KVM gets a huge performance boost from 64K pages, so I'm anxious to see this go in. I've submitted a few supporting patches for incidental problems caused by large pages, so I think it's just down to this patch itself now. -Hollis
