Update Virtual and Physical ports.
src/cpu/o3/alpha/cpu_impl.hh: Handle the PhysicalPort and VirtualPort in the ThreadState. src/cpu/o3/cpu.cc: Initialize the thread context. src/cpu/o3/thread_context.hh: Add new function to initialize thread context. src/cpu/o3/thread_context_impl.hh: Use code now put into function. src/cpu/simple_thread.cc: Move code to ThreadState and use the new helper function. src/cpu/simple_thread.hh: Remove init() in this derived class; use init() from ThreadState base class. src/cpu/thread_state.cc: Move setting up of Physical and Virtual ports here. Change getMemFuncPort() to connectToMemFunc(), which connects a port to a functional port of the memory object below the CPU. src/cpu/thread_state.hh: Update functions. --HG-- extra : convert_revision : ff254715ef0b259dc80d08f13543b63e4024ca8d
