[Xen-devel] Bind different tasks' evtchns to different vcpus of Dom0

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

Currently, all the event channels notify Dom0's vcpu0 -- this is not
nice considering the scalability.
The patch tries to bind different tasks' evtchns to different vcpus of
Dom0 when the bindings are initialized, and it can also dynamically
change the binding if a task actually gets run on another vcpu for some
reason.
Tests (Inb and OLTP) show the patch can improve the scalability to some
notable degree.
