According to the qemu patch, the model should be only adding features,
but I see rdtscp disappeared between SandyBridge and Haswell.  The
question is whether this is QEMU bug or not, do you have any info on
that?  If not, maybe we should cross-post ask in qemu-devel.

We also include 'sep' and 'fpu' on top of these things, but I recall
some conversation about qemu dropping 'sep' from some models lately, but
I have no idea about 'fpu' flag handling there either.

Thanks for pointing that out on the qemu-devel list:

I think we can safely assume the patch will make it in a few days, but
to be sure I'm giving you an ACK for when the patch gets into qemu's
upstream.

I pushed the patch now. Eduardo's patch got an ack and should make it into qemu 1.3.
