     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.
