[Qemu-devel] [PATCH 0/7] x86: Rework KVM-defaults compat code, enable kvm_pv_unhalt by default

[Eduardo Habkost <ehabkost@redhat.com>]

This series enables kvm_pv_unhalt by default on pc-*-2.11 and
newer.

To do that, I first reworked the existing
x86_cpu_change_kvm_default() logic to use compat_props instead,
so we don't need to make the chain of pc_compat_*() functions
grow.
