which of the BZs below are against 3.3?

OK, first of I am really excited that you guys are using the upstream kernel
and testing against the latest.

I think the issue I've seen before and it was due to a mix of vCPU hotplug code.
If I booted the kernel with max_cpus=16 (on the Linux command line) and did those
operations it worked. But it is a bug nonethless. Any ideas for a fix?
