Subject: [4/4] NUMA-Q: remove last traces of bus number mangling
Date: Tue, 12 Nov 2002 04:37:46 -0800 [thread overview]
Message-ID: <E18BaIc-0006a0-00@holomorphy> (raw)
This removes the last vestiges of the bus number mangling and passes the
local bus numbers directly to the low-level PCI config cycle routines.
