Just a note:
This will cause unecessary copy-on-write later.
(current remove_from_swap() can cause copy-on-write....)
But maybe copy-on-write is just minor case for migrating specified vmas.
For hotremove (I stops it now..), we should fix this later (if we can do).
If new SWP_TYPE_MIGRATION swp entry can contain write protect bit,
hotremove can avoid copy-on-write but things will be more complicated.
