Building s390:defconfig ... failed
Building s390:allnoconfig ... failed
Building s390:tinyconfig ... failed

We do noticed these set of build failures,

Seems like the following commit might have caused this
build break

drivers: provide devm_platform_ioremap_resource()
[ Upstream commit 7945f929f1a77a1c8887a97ca07f87626858ff42 ]

Yes. devm_ioremap_resource() is only defined with CONFIG_HAS_IOMEM,
That dependency was added to platform.c with commit 837ccda3480d
("drivers: depend on HAS_IOMEM for devm_platform_ioremap_resource()")
which wasn't backported.


Error log:
s390-linux-ld: drivers/base/platform.o: in function `devm_platform_ioremap_resource':
drivers/base/platform.c:97: undefined reference to `devm_ioremap_resource'
madrivers/base/platform.cke[1]: *** [Makefile:1061: vmlinux] Error 1
make: *** [Makefile:153: sub-make] Error 2

This also affects um:defconfig.
