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.
