[PATCH v3 00/15] Introduce virtio-mem <memory/> model



v3 of:

https://listman.redhat.com/archives/libvir-list/2021-February/msg00961.html

diff to v2:
- Dropped code that forbade use of virtio-mem and memballoon at the same
  time;
- This meant that I had to adjust memory accounting,
  qemuDomainSetMemoryFlags() - see patches 11/15 and 12/15 which are new.
- Fixed small nits raised by Peter in his review of v2

Michal Prívozník (15):
  virhostmem: Introduce virHostMemGetTHPSize()
  qemu_process: Deduplicate code in qemuProcessNeedHugepagesPath()
  qemu_process: Drop needless check in
    qemuProcessNeedMemoryBackingPath()
  qemu_capabilities: Introduce QEMU_CAPS_DEVICE_VIRTIO_MEM_PCI
  conf: Introduce virtio-mem <memory/> model
  qemu: Build command line for virtio-mem
  qemu: Wire up <memory/> live update
  qemu: Wire up MEMORY_DEVICE_SIZE_CHANGE event
  Introduce MEMORY_DEVICE_SIZE_CHANGE event
  qemu: Refresh the actual size of virtio-mem on monitor reconnect
  qemu: Account for both memballoon and virtio-mem
  qemuDomainSetMemoryFlags: Take virtio-mem into consideration
  virsh: Introduce update-memory-device command
  news: document recent virtio memory addition
  kbase: Document virtio-mem
