This series is based on v5.7-rc4. The patches are located at:
https://github.com/davidhildenbrand/linux.git virtio-mem-v4
This is basically a resend of v3 [1], now based on v5.7-rc4 and restested.
One patch was reshuffled and two ACKs I missed to add were added. The
rebase did not require any modifications to patches.
Details about virtio-mem can be found in the cover letter of v2 [2]. A
basic QEMU implementation was posted yesterday [3].

v3 -> v4:
- Move "MAINTAINERS: Add myself as virtio-mem maintainer" to #2
- Add two ACKs from Andrew (in reply to v2)
-- "mm: Allow to offline unmovable PageOffline() pages via ..."
-- "mm/memory_hotplug: Introduce offline_and_remove_memory()"
v2 -> v3:
- "virtio-mem: Paravirtualized memory hotplug"
-- Include "linux/slab.h" to fix build issues
-- Remember the "region_size", helpful for patch #11
-- Minor simplifaction in virtio_mem_overlaps_range()
-- Use notifier_from_errno() instead of notifier_to_errno() in notifier
-- More reliable check for added memory when unloading the driver
- "virtio-mem: Allow to specify an ACPI PXM as nid"
-- Also print the nid
- Added patch #11-#15
