SPARC64: implement addtional MMU faults related to nonfaulting load
This patch implements MMU faults caused by TTE.NFO and TTE.E: - access other than nonfaulting load to a page marked NFO should raise data_access_exception - nonfaulting load to a page marked with E bit should raise data_access_exception To distinguish nonfaulting loads, this patch extends (abuses?) the rw argument of get_physical_address_data(). rw is set to 4 on nonfaulting loads.
