COMPILE_TEST related patches for stable branches

Hi,

please consider adding the following patches to all stable branches.

v5.11.y:

ea29b20a8285 init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM

v4.9.y..v5.10.y:

334ef6ed06fa init/Kconfig: make COMPILE_TEST depend on !S390 ea29b20a8285 init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM

v4.4.y:

bc083a64b6c0 init/Kconfig: make COMPILE_TEST depend on !UML 334ef6ed06fa init/Kconfig: make COMPILE_TEST depend on !S390 ea29b20a8285 init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM

This will prevent issues with s390:randconfig, which may inadvertently enable COMPILE_TEST while HAS_IOMEM=n. This results in lots of useless compile errors and stray error reports from 0-day.

Thanks, Guenter
