These files are part of kernel, right. But distros tend to modify
everything, sometimes including kernel. Anyway, plain vanilla kernel
DOES define CONFIG_X86_L1_CACHE_SHIFT, in linux/autoconf.h, which is
included by linux/config.h and this one by asm/cache.h So everything
should be fine. And if something is missing then it's SuSE fault,
because they've broken something in kernel.
