From c8182f0016fb65a721c4fbe487909a2d56178135 Mon Sep 17 00:00:00 2001 From: Russ Anderson Date: Fri, 12 Dec 2008 11:07:00 -0600 Subject: sgi-xp: xpc needs to pass the physical address, not virtual Impact: fix crash xpc needs to pass the physical address, not virtual. Testing uncovered this problem. The virtual address happens to work most of the time due to the way bios was masking off the node bits. Passing the physical address makes it work all of the time.
