Several updates:

Browse source 
- The cleanup of the MI abuse of cpu_critical_*() is done.
- Note the VM change salc has been comitting.
- Note that jeffr finished making malloc() and free() not require Giant.
- I've just about finished all the td_ucred and p_ucred stuff now.
- Mark all the mutex changes I committed today as done.
- Add two new WIP entries for the work alc is still doing in the VM.
