[PATCH] Swapless page migration: rip out swap based logic
Rip the page migration logic out.
Remove all code that has to do with swapping during page migration.
This also guts the ability to migrate pages to swap. No one used that so lets
let it go for good.
Page migration should be a bit broken after this patch.
