From 4cbb1c1aaa04ce1fdcafbd87a02097c3873e33b1 Mon Sep 17 00:00:00 2001 From: Paul Saab Date: Wed, 31 May 2006 22:55:23 +0000 Subject: [PATCH] Fix minidumps to include pages allocated via pmap_map on amd64. These pages are allocated from the direct map, and were not previous tracked. This included the vm_page_array and the early UMA bootstrap pages.
