Prepare for 32bit pci root bus -v2: hpa said we should compare with (resource_size_t)~0 -v3: according to Linus to use MAX_RESOURCE instead. also need need to put related patches together -v4: according to Andrew, use min in cap_resource() Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <1265793639-15071-8-git-send-email-yinghai@kernel.org> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: H.
