[PATCH 0/8] RFC: vcpu pinning at qemu start

Hi guys,

Here's a first series of patch aiming at vcpu pinning support in qemu.
Ideally, as vcpu as just normal threads, the usual userspace tools can be used
to set cpu affinities mask.

However, It makes it very difficult to _start_ a vm with vcpus pinned, since
we don't know the thread ids from qemu in advance, nor do we know when are the
vcpus created.

The patches introduce a -cpu-map option, that, if specified, starts the virtual cpus
with the specified affinities.

Comments? Welcome. Random rants? Not welcome, but... how can I stop you? So go ahead!
