From d3e5e1a1b4f43bcfa1a34516e233911487c67307 Mon Sep 17 00:00:00 2001 From: Aaron Young Date: Wed, 28 Jun 2006 08:34:55 -0700 Subject: [PATCH] [IA64-SGI] fix prom revision checks in SN kernel The following patch fixes two spots in the SN kernel that check a fixed prom revision number to determine prom feature support. These checks are only valid on shub1 systems. They are invalid on shub2 systems which have a different prom with different revision numbers.
