    rwsem: Implement down_read_interruptible

    [ Upstream commit 31784cff7ee073b34d6eddabb95e3be2880a425c ]

    In preparation for converting exec_update_mutex to a rwsem so that
    multiple readers can execute in parallel and not deadlock, add
    down_read_interruptible.  This is needed for perf_event_open to be
    converted (with no semantic changes) from working on a mutex to
    wroking on a rwsem.
