Before this patch: (9 undefined symbols) ERROR: modpost: "devm_ioremap_resource" [drivers/crypto/ccree/ccree.ko] undefined! ERROR: modpost: "debugfs_create_regset32" [drivers/crypto/ccree/ccree.ko] undefined! ERROR: modpost: "devm_ioremap_resource" [drivers/media/rc/ir-hix5hd2.ko] undefined!

ERROR: modpost: "devm_ioremap_resource" [drivers/dma/qcom/hdma_mgmt.ko] undefined! ERROR: modpost: "of_address_to_resource" [drivers/dma/qcom/hdma_mgmt.ko] undefined! This patch only affected the last symbol above. And it covers of_iomap() in my build testing as well. After this patch: (8 undefined symbols) > All errors (new ones prefixed by >>, old ones prefixed by <<): > > ERROR: modpost: "devm_ioremap_resource" [drivers/crypto/ccree/ccree.ko] undefined! > ERROR: modpost: "debugfs_create_regset32" [drivers/crypto/ccree/ccree.ko] undefined! > ERROR: modpost: "devm_ioremap_resource" [drivers/media/rc/ir-hix5hd2.ko] undefined! > ERROR: modpost: "ioremap" [drivers/pcmcia/pcmcia.ko] undefined! > ERROR: modpost: "iounmap" [drivers/pcmcia/pcmcia.ko] undefined! >>> ERROR: modpost: "devm_platform_ioremap_resource" [drivers/char/xillybus/xillybus_of.ko] undefined! > ERROR: modpost: "devm_ioremap_resource" [drivers/dma/qcom/hdma.ko] undefined! > ERROR: modpost: "devm_ioremap_resource" [drivers/dma/qcom/hdma_mgmt.ko] undefined! I think that all of these arch/s390/ builds undefined symbols when CONFIG_HAS_IOMEM is not set are low priority (or no priority) for most people. -- ~Randy
