  memory: avoid updating ioeventfds for some address_space (2023-09-19 10:44:44 
+0200)

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

"Host Memory Backends" and "Memory devices" queue ("mem"):
- Support and document VM templating with R/O files using a new "rom"
  parameter for memory-backend-file
- Some cleanups and fixes around NVDIMMs and R/O file handling for guest
  RAM
- Optimize ioeventfd updates by skipping address spaces that are not
  applicable

----------------------------------------------------------------
David Hildenbrand (11):
  nvdimm: Reject writing label data to ROM instead of crashing QEMU
  softmmu/physmem: Distinguish between file access mode and mmap
    protection
  backends/hostmem-file: Add "rom" property to support VM templating
    with R/O files
  softmmu/physmem: Remap with proper protection in qemu_ram_remap()
  softmmu/physmem: Bail out early in ram_block_discard_range() with
    readonly files
  softmmu/physmem: Fail creation of new files in file_ram_open() with
    readonly=true
  softmmu/physmem: Never return directories from file_ram_open()
  docs: Don't mention "-mem-path" in multi-process.rst
  docs: Start documenting VM templating
  softmmu/physmem: Hint that "readonly=on,rom=off" exists when opening
    file R/W for private mapping fails
  machine: Improve error message when using default RAM backend id
