[Qemu-devel] [RFC 5/5] target-i386: Report QOM class name for CPU definitions

[Eduardo Habkost]

The new qom-type attributed will be used to indicate that the object-add
QMP command can be used to create CPU objects. This will let management
code to create multiple CPU objects from different classes and CPU
models and query for their information using QOM properties (like the
"feature-words" properties) in a single QEMU instance, instead of having
to re-run QEMU once for each CPU model.
