From: "Maciej S. Szmigiero" <maciej.szmigiero@oracle.com>

This is a continuation of the v7 of the patch series located here:
https://lore.kernel.org/qemu-devel/cover.1693240836.git.maciej.szmigiero@oracle.com/


Changes from v7:
* Rebase onto the current QEMU git master now that the David's memslots
patch series was merged there.

* Split out the hot-add part of the driver to a separate patch.

* Make "query-hv-balloon-status-report" only return a GenericError.

* Remove "@data" parameter description from "HV_BALLOON_STATUS_REPORT"
qapi since the build system complains about it.

* Reformat qapi descriptions according to received review comments.

* Collect David's and Markus' "Reviewed-by" and "Acked-by" tags.

* Fix a memslot name formatting issue.

* Add myself to MAINTAINERS.
