Subject: 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 .
