    cputime: Default implementation of nsecs -> cputime conversion · bfc3f028
    Frederic Weisbecker authored
    The architectures that override cputime_t (s390, ppc) don't provide
    any version of nsecs_to_cputime(). Indeed this cputime_t implementation
    by backend only happens when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y under
    which the core code doesn't make any use of nsecs_to_cputime().
    At least for now.
    We are going to make a broader use of it so lets provide a default
    version with a per usecs granularity. It should be good enough for most
