[PATCH v2 0/2] xen: sched/cpupool: more fixing of (corner?) cases

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

Hi all,

Here's v2 of this series. v1 is here:
 http://lists.xen.org/archives/html/xen-devel/2015-07/msg00647.html

As a quick recap, this is aimed at avoiding an host crash during shutdown or
suspension, it in the following cases:
 - when the boot cpu (i.e., most of the times, cpu 0) is not assigned to any
   cpupool,
 - when a (non default) cpupool only has one cpu (and that is not the boot
   cpu).

v1 was bigger, because of some preparatory/mechanical chages, which have been
applied already, so here's what remains.

Patch 2 is fully acked. Patch 1 won Juergen's ack, during v1, but I'm avoiding
sticking it there, as it changed a little bit, while addressing George's
comments.

Best Regards,
Dario
