From 545da94f924d52f80e2bbea99a8652f454889a2b Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sun, 28 Jan 2007 07:45:53 +1100 Subject: [PATCH] [POWERPC] Fix sys_pciconfig_iobase bus matching A stupid bug has been plaguing the sys_pciconfig_iobase on ppc64. It wasn't noticed until recently as it seems to not affect G5s but it's been causing problems running X servers on some other machines recently. The bus number matching was bogus.
