From 86ebacd360767f6a5cf9c8810977593dccf3f3da Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Wed, 8 Jun 2005 12:12:48 -0700 Subject: [PATCH] [IA64] Update comment to describe modes set in default control register. Christian Hildner pointed out that the comment did not match what the code does in cpu_init() when we set up the default control register. Patch based on suggestions from Ken Chen.
