Hi all,

this is a follow up to the patch we previously released here [1].
We are publishing new memory hot-remove support for arm64 memory hotplug,
which complements our initial hot-add patch.

For convenience, we are reposting in a single thread all the 5 patches
that compose the full memory hot-plug support, which are:
- The initial patchset by Scott Branden, orginally released in [2]
(2 patches).
- A second version of our hot-add patch, originally released in [1]
(1 patch).
- New hot-remove support complementing the hot-add patch. (2 patches).

The patches should apply cleanly on Linux 4.11-rc6
(commit: 39da7c509acff13fc8cb12ec1bb20337c988ed36).

We have performed tests and experiments on physical and emulated boards
and we are collecting results (along with more information) at the public
Web page at [3].

Any comments or feedback are, as usual, very much appreciated.
