-	/* What we used to do was lock a TLB entry into a specific
-	 * TLB slot, clear the page with interrupts disabled, then
-	 * restore the original TLB entry.  This was great for
-	 * disturbing the TLB as little as possible, but it meant
-	 * we had to keep interrupts disabled for a long time.
-	 *
-	 * Now, we simply use the normal TLB loading mechanism,
-	 * and this makes the cpu choose a slot all by itself.
-	 * Then we do a normal TLB flush on exit.  We need only
-	 * disable preemption during the clear.
