[PATCH] ppc64 iSeries: allow build with no PCI
This patch allows iSeries to build with CONFIG_PCI=n. This is useful for partitions that have only virtual I/O. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
