[v7 PATCH 00/10] Implement vcpu soft affinity for credit1

[Dario Faggioli <dario.faggioli@citrix.com>]

Hi Everyone,

This is v7 of the soft affinity series. For v6, and for a little history and
quick description of the feature, see here:

 http://lists.xen.org/archives/html/xen-devel/2014-05/msg03272.html

Wrt that, I, mostly:

 - fixed a bug present in patch 3, in case a domain is moved to a cpupool when
   the domain's vcpus have not been allocated yet (i.e., what happens when you
   create a domain not in the default cpupool);

 - introduced patch 5, to bump libxc and libxl SONAMEs;

 - changed the libxl bits (patch 7), as requestd and agreed during review.

All the patches have the acks they need from the relevant people, with the
exceptions of:
 - patch 5, that is new (tools maintainer's Ack required)
 - patch 9,8,7 (tools maintainer's Ack required)

A git branch with this version of the series can be found here:

 git://xenbits.xen.org/people/dariof/xen.git numa/per-vcpu-affinity-v7

Let me know if I need to change anything else.

Thanks and Regards,
Dario
