Subject: s390: use kbuild.h instead of defining macros in asm-offsets.c
X-Git-Tag: firefly_0821_release~20853
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4ca4d7bf7a650817c441073cb8d1c2c8dfbb9959;p=firefly-linux-kernel-4.4.55.git

s390: use kbuild.h instead of defining macros in asm-offsets.c

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
