[PATCH] RESEND - fix prom revision checks in SN kernel

From: Aaron Young <ayoung_at_google.engr.sgi.com>
Date: 2006-06-29 01:34:55
(Resend #1 - patch is now based off the aegl/linux-2.6.git tree)

The following patch fixes a few 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.
