[PATCH 3/8] Kconfig: unwanted config options for s390.

[Martin Schwidefsky]

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

Disable all configuration options in the common Kconfig files that
are of no interest to a s390 machine.

ok.

this one is bad in general and should probably be a select from the architecture,
but that should not stop you from adding another architecture...

Does it build? I don't see a point disabling this one just because there are
no users. Most architectures also don't have users for this one, but it
doesn't hurt be able to build it using allyesconfig.

The disable extension would help here, but I never got anywhere with it.
