  MAINTAINERS: Add an entry for Hyper-V Dynamic Memory Protocol (2023-11-06 14:08:10 +0100)

----------------------------------------------------------------
Hyper-V Dynamic Memory protocol driver.

This driver is like virtio-balloon on steroids for Windows guests:
it allows both changing the guest memory allocation via ballooning and
inserting pieces of extra RAM into it on demand from a provided memory
backend via Windows-native Hyper-V Dynamic Memory protocol.

* Preparatory patches to support empty memory devices and ones with
large alignment requirements.

* Revert of recently added "hw/virtio/virtio-pmem: Replace impossible
check by assertion" commit 5960f254dbb4 since this series makes this
situation possible again.

* Protocol definitions.

* Hyper-V DM protocol driver (hv-balloon) base (ballooning only).

* Hyper-V DM protocol driver (hv-balloon) hot-add support.

* qapi query-memory-devices support for the driver.

* qapi HV_BALLOON_STATUS_REPORT event.

* The relevant PC machine plumbing.

* New MAINTAINERS entry for the above.
