There could be two ways to solve the build issue on s390. One is to
conditionally include the "ide.h" file depending on whether CONFIG_IDE is
defined. The second method would be to make LKDTM dependent on IDE. But this
approach is not right as it would prevent usage of the module on s390
completely.

Done.
Thanks,

o This patch enables lkdtm to be built on s390
