RH-Commit: [2/2] 0a26a71236e68dd7feb5d2063254090e3852d6ba
The acpi index migration is simply broken before for all pre-RHEL8
branches. Don't migrate it for all of them.

RH-Commit: [1/2] c5b9cdf5791cd856207b7df7e2ef5df360ec8de4
vmstate_acpi_pcihp_use_acpi_index() was expecting AcpiPciHpState
as state but it actually received PIIX4PMState, because
VMSTATE_PCI_HOTPLUG is a macro and not another struct.
So it ended up accessing random pointer, which resulted
in 'false' return value and acpi_index field wasn't ever
sent.
However in 7.0 that pointer de-references to value > 0, and
destination QEMU starts to expect the field which isn't
sent in migratioon stream from older QEMU (6.2 and older).
As result migration fails with:
qemu-system-x86_64: Missing section footer for 0000:00:01.3/piix4_pm
qemu-system-x86_64: load of migration failed: Invalid argument
In addition with QEMU-6.2, destination due to not expected
state, also never expects the acpi_index field in migration
stream.
Q35 is not affected as it always sends/expects the field as
long as acpi based PCI hotplug is enabled.
Fix issue by introducing compat knob to never send/expect
acpi_index in migration stream for 6.2 and older PC machine
types and always send it for 7.0 and newer PC machine types.

Subject: [PATCH 3/3] hw/arm/virt: Do not load efi-virtio.rom for all
virtio-net-pci variants
RH-Author: Eric Auger <eric.auger@redhat.com>
RH-MergeRequest: 344: hw/arm/virt: Do not load efi-virtio.rom for any virtio-net-pci variants
RH-Jira: RHEL-14870
RH-Acked-by: Gerd Hoffmann <None>
RH-Acked-by: Sebastian Ott <None>
RH-Commit: [1/1] ffeaa78ad0a1cff5b49009dfb32d25e5cadc0e05
Upstream: RHEL-only
Brew: http://brewweb.engineering.redhat.com/brew/taskinfo?taskID=5785640
Currently arm_rhel_compat just sets the romfile to "" for
virtio-net-pci and not for transitional and non transitional
variants. However, on aarch64 RHEL, efi-virtio.rom is not
shipped so transitional and non-transitional variants cannot
be used and the following error is obeserved:
"Could not open option rom 'efi-virtio.rom': No such file or directory"
In practice, we do not need any rom file for those virtio-net-pci
variants either because edk2 already brings the full functionality.
So let's change the applied compat to cover all the variants. While
at it also change the way arm_rhel_compat is applied. Instead of
applying it from the latest _virt_options(), which is error prone
when upgrading the machine type, let's apply it before calling
*virt_options in the non abstract machine class. That way the setting
will apply to any machine type without any need to add it in any
future machine types.
We don't really care keeping non void romfiles for transitional and
non transitional devices on previous machine types because this
was not working anyway.
