[PATCH 0/4] hw/i386/pc: Remove deprecated 3.0 machines

[Philippe Mathieu-Daudé]

1 y.o. dust Thomas asked me to post:

The versioned 'pc' and 'q35' machines up to 3.0 been marked
as deprecated two releases ago, and are older than 6 years,
so according to our support policy we can remove them.

[PATCH 1/4] hw/i386/pc: Remove deprecated pc-q35-3.0 and pc-i440fx-3.0 machines

[Philippe Mathieu-Daudé]

These machines has been supported for a period of more than 6 years.
According to our versioned machine support policy (see commit
ce80c4fa6ff "docs: document special exception for machine type
deprecation & removal") they can now be removed.

[PATCH 3/4] target/i386/kvm: Remove X86CPU::hyperv_synic_kvm_only field

[Philippe Mathieu-Daudé]

The X86CPU::hyperv_synic_kvm_only boolean (see commit 9b4cf107b09
"hyperv: only add SynIC in compatible configurations") was only set
in the pc_compat_3_0[] array, via the 'x-hv-synic-kvm-only=on'
property. We removed all machines using that array, lets remove that
property and all the code around it.
