powerpc/vas: Define vas_win_id() Define an interface to return a system-wide unique id for a given VAS window. The vas_win_id() will be used in a follow-on patch to generate an unique handle for a user space receive window. Applications can use this handle to pair send and receive windows for fast thread-wakeup. The hardware refers to this system-wide unique id as a Partition Send Window ID which is expected to be used during fault handling. Hence the "pswid" in the function names.
