Not a very useful commit message.
This makes me wonder, though.
What happens if a user mmaps a 30MB memory region, registers it
with KSM and then unmaps the middle 10MB?
User cant break 30MB into smaller one.
That mean that when you regisiter memory region that is X mb size, you
can only remove it (as a whole), or add new region.
This should answer the next question you had about why i have just the
start address for removing the regions.
