The name of PCI root bus's M64 resource isn't initialized properly. When dumping "/proc/iomem", "<BAD>" is seen for those M64 resources on PCI root buses. ~# cat /proc/iomem | grep -e "BAD" 3b0000000000-3b0fefffffff : <BAD> 3b1000000000-3b1fefffffff : <BAD> 3c0000000000-3c0fefffffff : <BAD> 3c1000000000-3c1fefffffff : <BAD> 3c2000000000-3c2fefffffff : <BAD> This fixes the issue by setting the name of PCI root bus's M64 resource to that of PHB's device node full name. With the patch, no "<BAD>" is seen from "/proc/iomem". Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
