[PATCH v2] xen: sched: introduce hard and soft affinity in credit 2 scheduler
...on now chooses the vCPU with the most credit that has hard affinity
and maybe soft affinity for the given pCPU. If it does not have soft affinity
and there is another vCPU that prefers to run on the given pCPU, then as long
as it has at least a certain amount of credit (currently defined as half of
CSCHED_CREDIT_INIT, but more testing is needed to determine the best value)
then it is chosen instead.
This patch depends on Dario Faggioli''s patch set "Implement vcpu soft
affinity for credit1" currently in version 5 for vcpu->cpu_hard_affinity
and vcpu->cpu_soft_affinity defined in sched.h...

Address some credit2 issues. This patch series, along with the recent
changes to the cpupools interface, should address some of the strange
credit2 instability.
