8 * s390 uses its own implementation for per cpu data, the offset of
9 * the cpu local data area is cached in the cpu's lowcore memory.
10 * For 64 bit module code s390 forces the use of a GOT slot for the
11 * address of the per cpu variable. This is needed because the module
12 * may be more than 4G above the per cpu area.
