pcibus_to_node can return -1 if we cannot determine which node a pci bus is on. If passed -1, cpumask_of_node will negatively index the lookup array and pull in random data: # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus 00000000,00000003,00000000,00000000 # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist 64-65 Change cpumask_of_node to check for -1 and return cpu_all_mask in this case: # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus ffffffff,ffffffff,ffffffff,ffffffff # cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist 0-127 Signed-off-by: Anton Blanchard <anton@samba.org> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Andrew Morton <akpm@linux-foundation.org> Patchwork: http://patchwork.linux-mips.org/patch/831/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
