clang W=1 warns about missing prototypes:
>> arch/s390/kernel/vdso64/getcpu.c:8:5: warning: no previous prototype for function '__s390_vdso_getcpu' [-Wmissing-prototypes]
int __s390_vdso_getcpu(unsigned *cpu, unsigned *node, struct getcpu_cache *unused)

Add a local header file in order to get rid of this warnings.
