Analyze and fix the following issue in the Linux kernel code: [POWERPC] Fix up the OF functions to only do PCI stuff if PCI is actually configured
Problem Details: The original problem that inspired this patch was solved quite some time ago (Turning off PCI didn't work), but this patch neatens things up a little (I think), by putting all the PCI stuff inside a single CONFIG_PCI block. It also removes the OF PCI bus matching entries if CONFIG_PCI is off. Signed-...

Problem Details: This patch is suitable for just about any 2.6 kernel. It should go in 2.6.19 and 2.6.18.2 and possible even the .17 and .16 stable series. This is a long standing bug that seems to have only recently become apparent, presumably due to increasing use of NFS over TCP - many distros seem to be making it...
