From 853ad6c2e752215237e7fb26d681ed0008dd081a Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 20 Dec 2007 14:54:48 +1100 Subject: [PATCH] [POWERPC] pci32: Remove obsolete PowerMac bus number hack The 32 bits PCI code carries an old hack that was only useful for G5 machines. Nowdays, the 32 bits kernel doesn't support any of those machines anymore so the hack is basically never used, so remove it.
