[PATCH] s390: remove kvm_types.h from Kbuild

[Randy Dunlap]

kvm_types.h is mandatory in include/asm-generic/Kbuild so having it
in another Kbuild file causes a warning. Remove it from the arch/
Kbuild file to fix the warning.

../scripts/Makefile.asm-headers:39: redundant generic-y found in ../arch/s390/include/asm/Kbuild: kvm_types.h

This should go via perf/core from the tip tree, since Peter's not-yet upstream
commit 01122b89361e ("perf: Use EXPORT_SYMBOL_FOR_KVM() for the mediated
APIs") adds the mandatory-y statement to include/asm-generic/Kbuild.

Peter?

Let me see if I can manage to apply a patch I don't have ;-)
