Essentially a resend with ACKs/RBs. If I don't get any more comments
I'll queue this to my mem-next tree next week.


Working on adding multi-memslot support for virtio-mem (teaching memory
device code about memory devices that can consume multiple memslots), I
have some preparatory cleanups in my queue that make sense independent of
the actual memory-device/virtio-mem extensions.

v3 -> v4:
- Added RBs and ACKs

v2 -> v3:
- "memory-device: Introduce machine_memory_devices_init()"
-- Declare the function in hw/boards.h
- "hw/loongarch/virt: Use machine_memory_devices_init()"
-- Use VIRT_HIGHMEM_BASE
-- No need to include memory-device.h
- "hw/i386/pc: Remove PC_MACHINE_DEVMEM_REGION_SIZ"
-- Add more details why it's ok to the patch description
- Adjust to memory_devices_init() -> machine_memory_devices_init()
- Add RBs

v1 -> v2:
- Allocate ms->device_memory only if the size > 0.
- Split it up and include more cleanups

David Hildenbrand (10):
  memory-device: Unify enabled vs. supported error messages
  memory-device: Introduce machine_memory_devices_init()
  hw/arm/virt: Use machine_memory_devices_init()
  hw/ppc/spapr: Use machine_memory_devices_init()
  hw/loongarch/virt: Use machine_memory_devices_init()
  hw/i386/pc: Use machine_memory_devices_init()
  hw/i386/acpi-build: Rely on machine->device_memory when building SRAT
  hw/i386/pc: Remove PC_MACHINE_DEVMEM_REGION_SIZE
  memory-device: Refactor memory_device_pre_plug()
  memory-device: Track used region size in DeviceMemoryState

Queued to

https://github.com/davidhildenbrand/qemu.git mem-next

Will probably send a PR later this week.
