Log Message:
Track which process a CPU is running/has last run on by adding a
p_cpu member to struct proc.  Use this in certain places when
accessing scheduler state, etc.  For the single-processor case,
just initialize p_cpu in fork1() to avoid having to set it in the
low-level context switch code on platforms which will never have
multiprocessing.

While I'm here, comment a few places where there are known issues
for the SMP implementation.
