2006-03-28Move TLB faults into the normal Fault code. The TLB no longer fills in IPRs ↵Kevin Lim
through its own fault() method; this is handled by the fault's invoke() methods. arch/alpha/faults.cc: Move TLB fault code into the normal fault invoke() method. arch/alpha/faults.hh: Move DTB/ITB fault handling code into their own class with a specific invoke() method. Have DTB/ITB faults derive from these classes. Unfortunately the DtbAlignmentFault is somewhat odd; it's a normal alignment fault, but it must also set some specific IPRs. arch/alpha/tlb.cc: arch/alpha/tlb.hh: Setting IPRs is now handled through the fault itself. --HG-- extra : convert_revision : 5cb92ce2186ff79f632bfcbc9ba62a8a04400eae
