[PATCH] ppc32: i8259 PIC should not be initialized if PCI is not configured
Trying to initialize the i8259 PIC will not work if CONFIG_PCI is not enabled. The kernel hangs if the initialization is tried. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
