Hey,

This patch series expose the actual thread id of each cpu via the qemu
monitor. It is done through "info cpus", which I though would be the
most natural command to do it. (If you disagree, please voice it)

Goal is to allow tools like libvirt to easily grab it and feed taskset
for thinks like cpu pinning, etc

AFAIK, qemu runs all cpus in the same process, so for plain qemu, all cpus
will show the same id. But KVM can benefit from it, by overriding this data
in its ap initialization

Of the whole series, only the last patch is kvm-specific.

Many thanks to Anthony, who pointed me that this approach was possible.



Applied all, thanks.
