add write/read functions that have endian conversions in them
when we get a virtual port delete it (even though delete does nothing in these cases) src/arch/alpha/linux/system.cc: src/arch/alpha/stacktrace.cc: src/base/remote_gdb.cc: src/cpu/simple_thread.cc: when we get a virtual port delete it (even though delete does nothing in this case) src/mem/port.hh: src/mem/vport.hh: add write/read functions that have endian conversions in them --HG-- extra : convert_revision : 163e05cc038c461f95c92f8ce55422033f9ea513
