Log message:
Switch from TSS-per-process to TSS-per-CPU, placing the TSS right
next to the cpu's GDT, also making the double-fault stack per-CPU,
leaving it at the top of the page of the CPU's idle process. Inline
pmap_activate() and pmap_deactivate() into the asm cpu_switchto
routine, adding a check for the new pmap already being marked as
active on the CPU. Garbage collect the hasn't-been-used-in-years
GDT update IPI.
Tested by many; ok mikeb@, kettenis@
