This is looking quite a bit nicer than the last post. One nit on the
changelogs: please make an effort to connect the patches. If you
introduce a function here but don't use it, tell us where it _will_ be used.
As it stands, this series _looks_ like it is touching 3 disjoint things:
* pg_data_t
* e820
* memblocks
It would be valuable to spend a few sentences to connect the dots.
Subsystem prefixes are also highly preferred. Perhaps:
mm: Extend memblock to support memory encryption
or
mm/memblock: Tag memblocks with crypto capabilities
It also helps make it obvious that this series touches both core mm/ and
arch/x86/ code.
