The work the VAX pmap does in cpu_swapout() and cpu_swapin() seems
* Before a process is swapped out, pmap_collect() is called to
release any resources for that process. cpu_swapout() doesn't
really need to do it; the work should be in pmap_collect().
* cpu_swapin() shouldn't need to validate all of the PTEs for
the U-area, since the upper levels in the VM system explicitly
wire the space, so pmap_enter() will be called to do the job.
The only think you really need to do there is to set the redzone
Am I missing something?
