This series is based on latest linux-next. The patches are located at: https://github.com/davidhildenbrand/linux.git virtio-mem-v3
Patch #1 - #10 where contained in v2 and only contain minor modifications (mostly smaller fixes). The remaining patches are new and contain smaller optimizations.
Details about virtio-mem can be found in the cover letter of v2 [1]. A basic QEMU implementation was posted yesterday [2].

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
