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.
