Luoqi Chen 5206bca10a Enable vmspace sharing on SMP. Major changes are, ... - %fs register is added to trapframe and saved/restored upon kernel entry/exit. - Per-cpu pages are no longer mapped at the same virtual address. - Each cpu now has a separate gdt selector table. A new segment selector is added to point to per-cpu pages, per-cpu global variables are now accessed through this new selector (%fs). The selectors in gdt table are rearranged for cache line optimization. - fask_vfork is now on as default for both UP and SMP. - Some aio code cleanup.
