From bef5c1203e8b821e3eeb308fe0fec1cd4a4b82aa Mon Sep 17 00:00:00 2001
From: Artur Grabowski <art@cvs.openbsd.org>
Date: Wed, 9 May 2001 15:31:29 +0000
Subject: More sync to NetBSD.

 - Change pmap_change_wiring to pmap_unwire because it's only called that way.
 - Remove pmap_pageable because it's seldom implemented and when it is, it's
   either almost useless or incorrect. The same information is already passed
   to the pmap anyway by pmap_enter and pmap_unwire.
