From alan@lxorguk.ukuu.org.uk Mon Aug 17 12:36:26 2009 From: Alan Cox Date: Fri, 14 Aug 2009 15:42:18 +0100 Subject: Staging: sep: kick out various fields we can prove are not needed To: greg@kroah.com, mark.a.allyn@intel.com Message-ID: <20090814144156.6066.814.stgit@localhost.localdomain> From: Alan Cox #1: sep->cache_addr is assigned to sep->rar_addr and never changed sep->rar_addr is never assigned after this point #2: sep->cache_bus ditto for sep->rar_bus #3 sep->rar_region_addr is assigned but necer used #4 sep->io_addr is in fact private to the probe function and the same as the reg_addr #5 The remainig sep->io fields are in fact function locals #6 sep->message_shared_area is assigned once from sep->shared_area sep->shared_area does not then change #7 sep->shared_addr and sep->shared_area_addr are the same thing, ditto for the bus addresses.
