[Qemu-devel] [RFC 0/2] GET_EMULATED_CPUID support with "allow-emulation" option

[Eduardo Habkost <ehabkost@redhat.com>]

This implements GET_SUPPORTED_CPUID support using an explicit option for it:
"allow-emulation". We don't want any emulated feature to be enabled by accident,
so they will be enabled only if the user explicitly wants to allow them.

This requires a few fixes to the qom-cpu tree which haven't been merged yet.
