You should still do randconfig testing for s390 (for other problems), but the robot has been sending out a lot of build errors similar to this one, using different randconfig files. I am just saying that you can find all of the ioremap/iounmap/devm_io* type build errors in one kernel config file as described above. > > Best Regards, > Rong Chen > >> >> $ make allmodconfig >> $ scripts/config -d PCI ## this also disables HAS_IOMEM >> $ make oldconfig >> $ make all >> >> The latter gives a full list of drivers etc. that use iomemp/ioremap etc. as >> well as dev_io* variants instead of just a few random ones. >> >> >>> All errors (new ones prefixed by >>): >>> >>> s390-linux-ld: drivers/net/ethernet/xilinx/ll_temac_main.o: in function >>> `temac_probe': >>> ll_temac_main.c:(.text+0x39b6): undefined reference to >>> `devm_platform_ioremap_resource_byname' >>>>> s390-linux-ld: ll_temac_main.c:(.text+0x3a4c): undefined reference to >>>>> `devm_platform_ioremap_resource_byname' >>> s390-linux-ld: ll_temac_main.c:(.text+0x3bce): undefined reference to >>> `devm_ioremap' >>> s390-linux-ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.o: in >>> function `axienet_probe': >>> xilinx_axienet_main.c:(.text+0x844): undefined reference to >>> `devm_ioremap_resource' >> _______________________________________________ -- ~Randy
