Subject: procfs: do not confuse jiffies with cputime64_t
Commit 2a95ea6c0d129b4568fb64e1deda16ceb20e6636 ("procfs: do not overflow get_{idle,iowait}_time for nohz") did not take into account that one some architectures jiffies and cputime use different units. Instead of converting the usec value returned by get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function usecs_to_cputime64 to convert it to the correct unit of cputime64_t.
