From 8681b974c1eeacabbf4424174e9b0e707bd534e5 Mon Sep 17 00:00:00 2001
From: David Greenman <dg@FreeBSD.org>
Date: Thu, 11 Mar 1999 18:28:46 +0000
Subject: [PATCH] Increased kernel virtual address space to 1GB. NOTE: You MUST
 have fixed bootblocks in order to boot the kernel after this! Also note that
 this change breaks BSDI BSD/OS compatibility. Also increased default NKPT to
 17 so that FreeBSD can boot on machines with >=2GB of RAM. Booting on
 machines with exactly 4GB requires other patches, not included.
