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.
