s390: use kbuild.h instead of defining macros in asm-offsets.c
Browse files Browse the repository at this point in the history
New version that does not preserve the marker. Arch maintainers indicate
that the marker functionality is is not needed anymore.

Note you may simplify the s390 asm-offsets.c code further if you use the
OFFSET() macro instead of the DEFINE. See kbuild.h
