This series enables memory hot remove functionality on arm64 platform. This
is based on Linux 5.5-rc6 and particularly deals with a problem caused when
boot memory is attempted to be removed.

Hello Will,

Unfortunately, this results in a conflict with mainline since the arm64
-next branches are based on -rc3 and there was a fix merged after that
(feee6b298916 ("mm/memory_hotplug: shrink zones when offlining memory"))
which changes the type of __remove_pages().

Right, that fix went in last couple of weeks.

So I think I'll leave this for 5.7.

Just wondering if there is any chance this can still make it to 5.6
or its already too late ?
