Andreas,

Taking in account that we agreed that static properties are convenient
for using with Devices and that CPU is Device now,

Could you consider applying patches [3-10/16] to your qom-cpu branch, please.

As minimum they consolidate x86 CPU properties in one properties array
and are nice codebase cleanup. Patches 3-4, replace custom setters/getters
with generic ones, replacing them with DEFINE_PROP_UINT32() one-liners.
As you can see Anthony says it's reasonable thing to do:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg215491.html

As side effect of conversion it allows to leverage currently working
"legacy" commands -device/(HMP) info qtree/(QMP)device-list-properties
for x86 CPUs which provides immediate benefits (without waiting on
rewrite of everything in QOM way).

The rest of series, I'll respin utilizing current QOM infrastructure more
and make bit->name conversion local to x86 CPU code as you've suggested.
