Subject: Add downstream x86_64 versioned 'pc' & 'q35' machine types
Adding changes to add RHEL machine types for x86_64 architecture.
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>
---
Rebase notes (9.1.0):
- Merged pc_q35_machine_rhel_options back into
pc_q35_machine_options to reduce delta to upstream
- Convert to new DEFINE_(I440FX|Q35)_MACHINE macros
- Moved x86 cpu deprecation note to device disable patch
Rebase notes (10.0.0 rc0):
- Do not use bugfix macro for q35
- Use upstream compat
- Add downstream specific compat
- Fixing rhel-9.4 compat issue
Merged patches (9.1.0):
- 043ad5ce97 Add upstream compatibility bits (partial)
Merged patches (10.0.0 rc0):
- 03502faf70 Add upstream compatibility bits
- 6be70c681b x86: ensure compatibility of pc-q35-rhel9*
- d6b6ae511c x86: create new pc-q35 machine type for rhel 9.6
- fcf4da60bd x86: create pc-i440fx machine type for rhel10
- 4acb295fa2 x86: create pc-q35 machine type for rhel10
- 0489497df8 x86: remove deprecated rhel machine types
- f53dbf7532 remove stale compat definitions (partial)
- 379e14ba88 pc: q35: Bump max_cpus to 4096 vcpus
- d93fcb3940 virtio-net: disable USO for all RHEL9 (partial)
