X-Git-Tag: cleanup-for-v3.18~17^2~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4afba24e5fc2626a3c604ec990539572f6662ff9;p=pandora-kernel.git sparc64: Skip bogus PCI bridge ranges. It seems that when a PCI Express bridge is not in use and has no devices behind it, the ranges property is bogus. Specifically the size property is of the form [0xffffffff:...], and if you add this size to the resource start address the 64-bit calculation will overflow. Just check specifically for this size value signature and skip them. Signed-off-by: David S. Miller --- Reading git-diff-tree failed
