  virtio-mem: Mark memslot alias memory regions unmergeable (2023-10-12 14:15:22 +0200)

----------------------------------------------------------------
Hi,

"Host Memory Backends" and "Memory devices" queue ("mem"):
- Support memory devices with multiple memslots
- Support memory devices that dynamically consume memslots
- Support memory devices that can automatically decide on the number of
  memslots to use
- virtio-mem support for exposing memory dynamically via multiple
  memslots
- Some required cleanups/refactorings

----------------------------------------------------------------
David Hildenbrand (18):
      vhost: Rework memslot filtering and fix "used_memslot" tracking
      vhost: Remove vhost_backend_can_merge() callback
      softmmu/physmem: Fixup qemu_ram_block_from_host() documentation
      kvm: Return number of free memslots
      vhost: Return number of free memslots
      memory-device: Support memory devices with multiple memslots
      stubs: Rename qmp_memory_device.c to memory_device.c
      memory-device: Track required and actually used memslots in DeviceMemoryState
      memory-device,vhost: Support memory devices that dynamically consume memslots
      kvm: Add stub for kvm_get_max_memslots()
      vhost: Add vhost_get_max_memslots()
      memory-device,vhost: Support automatic decision on the number of memslots
      memory: Clarify mapping requirements for RamDiscardManager
      virtio-mem: Pass non-const VirtIOMEM via virtio_mem_range_cb
      virtio-mem: Update state to match bitmap as soon as it's been migrated
      virtio-mem: Expose device memory dynamically via multiple memslots if enabled
      memory,vhost: Allow for marking memory device memory regions unmergeable
      virtio-mem: Mark memslot alias memory regions unmergeable
