the TLB and ~1600 if it is not. Therefore, it is more effecient to invalidate the TLB after operations that use CMAP rather than before. - So that the tlb is invalidated prior to switching off of a processor, we must change the switchin functions to switchout functions. - Remove td_switchout from the thread and move it to the x86 pcb. - Move the code that calls switchout into swtch.s. These changes make this optimization truely x86 specific.
