Changes since v4:
- As suggested by Michal Hocko,
- Simplify logic in online_pages_block() by using get_order().
- Seperate out removal of prefetch from __free_pages_core().
Changes since v3:
- Renamed _free_pages_boot_core
They not only increase the code footprint, they actually make things
slower rather than faster. Remove them as contemporary hardware doesn't
need any hint.

Hi,
I am not sure, but if we are going to use that function from the
memory-hotplug code,
we might want to rename that function to something more

This seems like almost complete copy of __free_pages_boot_core(),
could
you do some code reuse instead? I think Michal Hocko also suggested
that.
Yes, please try to reuse as much code as possible
