sched/cputime: Remove generic asm headers
cputime_t is now only used by two architectures: * powerpc (when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y) * s390 And since the core doesn't use it anymore, we don't need any arch support from the others. So we can remove their stub implementations. A final cleanup would be to provide an efficient pure arch implementation of cputime_to_nsec() for s390 and powerpc and finally remove include/linux/cputime.h .
