This patch extends the 'Parent::session()' and 'Root::session()' functions with an additional 'affinity' parameter, which is inteded to express the preferred affinity of the new session. For CPU sessions provided by core, the values will be used to select the set of CPUs assigned to the CPU session. For other services, the session affinity information can be utilized to optimize the locality of the server thread with the client. For example, to enable the IRQ session to route an IRQ to the CPU core on which the corresponding device driver (the IRQ client) is running.
