Hi,

This v6 is based on the master branch at the commit 0fc482b73d8e
("Merge tag 'pull-aspeed-20260105' of https://github.com/legoater/qemu
into staging").

Since there's the discussion around fw_cfg_init_io_nodma() [*], v6
doesn't include that cleanups. Therefore, comparing v5, v6 has *very*
minimal changes and most of patches have been reviewed (except patch 15
- I think it needs an additianl review :-) ).

Thanks for your patience and review!


Introduction
============

A brief introduction from Philippe's v4:

The versioned 'pc' and 'q35' machines up to 2.12 been marked
as deprecated three releases ago, and are older than 6 years,
so according to our support policy we can remove them.

This series only includes the 2.6 and 2.7 machines removal,
as it is a big enough number of LoC removed. Rest will
follow.


Change Log
==========

(Main) changes since v5:
 * Merge pc & q35 changes for testing DSDT tables into one patch and
   simplify the commit message.
 * Reorganize S-o-b and collect review tags from Igor. 

(Main) changes since v4:
 * Completely remove the legacy CPU hotplug approach.
   - New patch 2-8.
   - Test CPU hot-plug & hot-unplug via qmp.

 * Keep "dma_enabled" property in fw_cfg_io_properties[] since Sun4u &
   Sun4v are still using it.
   - About more details, please see commit message of patch 15.

 * Temporarily keep these properties: "cpuid-0xb" (of X86CPU),
   "fill-mtrr-mask" (of X86CPU), "version" (of IOAPICCommonState).
   - These properties will be deprecated first before removal, in
     another series.

 * Keep "l3-cache" (of X86CPU) and "page-per-vq" (of VirtIOPCIProxy),
   since they are still in use (e.g., libvirt).
