What is more likely is that you will get pushed to doing something like
periodically scanning memory as part of a separate power management
module and calling into PASR if regions of memory that are found that
can be powered down in some ways.

With this solution, we need in any case to add some hooks in the allocator
to ensure the pages being allocated are refreshed.

Why do you insist on making this happen at page level when you're only
able to power off *much* larger chunks?
