Subject: [PATCH v3 00/15] virtio-mem: paravirtualized memory

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

[2] https://lkml.kernel.org/r/20200506094948.76388-1-david@redhat.com

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
