Original version of that patch (commit a89941816726) had to be reverted
due to Xen allocating irqs in its cpu_up ops.

The first patch moves allocations into hotplug notifiers and the second
one restores the original patch (with minor adjustments to new hotplug
framework)

Boris Ostrovsky (2):
  xen/x86: Move irq allocation from Xen smp_op.cpu_up()
  hotplug: Prevent alloc/free of irq descriptors during cpu up/down
    (again)
