Optimistic spinning is only used by the xadd variant of rw-semaphores. Make sure that we use the old version of the __RWSEM_INITIALIZER macro for systems that rely on the spinlock one, otherwise warnings can be triggered, such as the following reported on an arm box: ipc/ipcns_notifier.c:22:8: warning: excess elements in struct initializer [enabled by default] ipc/ipcns_notifier.c:22:8: warning: (near initialization for 'ipcns_chain.rwsem') [enabled by default] ipc/ipcns_notifier.c:22:8: warning: excess elements in struct initializer [enabled by default] ipc/ipcns_notifier.c:22:8: warning: (near initialization for 'ipcns_chain.rwsem') [enabled by default] Signed-off-by: Davidlohr Bueso <davidlohr@hp.com> Signed-off-by: Peter Zijlstra <peterz@infradead.org> Cc: Tim Chen <tim.c.chen@linux.intel.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Paul McKenney <paulmck@linux.vnet.ibm.com> Cc: Michel Lespinasse <walken@google.com> Cc: Peter Hurley <peter@hurleysoftware.com> Cc: Alex Shi <alex.shi@linaro.org> Cc: Rik van Riel <riel@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: "H.
