[PATCH v2 4/5] ACPI/PCI: Warn if we have to "guess" host bridge node information

2014-04-18 Thread Myron Stowe
The vast majority of platforms are not supplying ACPI _PXM (proximity) information corresponding to host bridge (PNP0A03/PNP0A08) devices resulting in sysfs "numa_node" values of -1 (NUMA_NO_NODE) [1]: # for i in /sys/devices/pci\:00/*/numa_node; do cat $i; done | uniq -1 # find /sys/ -n
