fixes for new memory system
SConscript: comment out most devices add vport.cc arch/alpha/arguments.cc: arch/alpha/arguments.hh: push in alpha name space fix for new memory system arch/alpha/faults.cc: arch/alpha/faults.hh: Added an unimplemented fault that can be returned if a certain function isn't implemented arch/alpha/freebsd/system.cc: arch/alpha/linux/system.cc: arch/alpha/stacktrace.cc: arch/alpha/system.cc: arch/alpha/tlb.hh: arch/alpha/tru64/system.cc: fixed for new memory system arch/alpha/tlb.cc: fixed for new memory system removed code that seems to have no purpose arch/alpha/vtophys.cc: arch/alpha/vtophys.hh: fixed for new memory system put in namespace AlphaISA base/remote_gdb.cc: fix for new memory system cpu/cpu_exec_context.cc: cpu/cpu_exec_context.hh: cpu/exec_context.hh: create two ports one of physical accesses and one for superpage accesses Add functions getVirtPort() getPhysPort() delVirtPort(). To get statically allocated physical or virtual ports or if an execcontext is passed in get a dynamically allocated virtual port dev/alpha_console.cc: dev/alpha_console.hh: Redo for new memory system dev/io_device.cc: dev/io_device.hh: new I/O devices for new memory system kern/linux/events.cc: kern/linux/printk.cc: kern/linux/printk.hh: kern/tru64/dump_mbuf.hh: kern/tru64/printf.cc: kern/tru64/printf.hh: Arguments now in namespaces kern/tru64/tru64_events.cc: mem/bus.cc: fix for new memory syste mem/physical.hh: new addressranges function getPort should be public mem/port.hh: Add write/read methods to functional port update getDeviceAddrRanges to have a list of both snoops and response lists sim/pseudo_inst.cc: sim/system.cc: sim/system.hh: Update for new mem system sim/vptr.hh: comment out code and replace with panics This will need to be fixed at some point, but it's not easy. --HG-- extra : convert_revision : 41f41f422cfbab3751284d55cccb6ea64a7956e2
