From 2580d306ab52773a1634fe5c0499a8eab6895595 Mon Sep 17 00:00:00 2001
From: thorpej <thorpej@NetBSD.org>
Date: Wed, 26 May 1999 19:16:28 +0000
Subject: [PATCH] Change the vm_map's "entries_pageable" member to a r/o flags
 member, which has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means
 "pageable", not "allocate vm_map_entry's from non-static pool", so update all
 map creations to reflect that.  INTRSAFE maps are maps that are used in
 interrupt context (e.g. kmem_map, mb_map), and thus use the static map entry
 pool (XXX as does kernel_map, for now).  This will eventually change now
 these maps are locked, as well.
