[0/3] xen: Fix some bugs in scheduling

Message

Some bugs I found when trying to find a problem with cpu-on/offlining
in core scheduling mode.

Patches 1 and 3 are fixing observed problems, while patch 2 is more
of a theoretical issue.

Juergen Gross (3):
  xen/sched: allow rcu work to happen when syncing cpus in core
    scheduling
  xen/sched: fix theoretical races accessing vcpu->dirty_cpu
  xen/cpupool: fix removing cpu from a cpupool
