Fix mapping of working set list page -- it should be local.
Get rid of MI_MAKE_LOCAL_PAGE and use ValidKernelPdeLocal/ValidKernelPteLocal consistently. This is what they exist for!
We should now hopefully not be creating any global pages when we don't want them.
Next step; fix flushing.
Bonus: Use the right lock in MiSessionLeader
