Martin Schwidefsky 70f5dc514c [S390] cputime: fix overflow on 31 bit systems 
The cputime_to_msecs / cputime_to_clock_t and cputime64_to_clock_t
cause fixpoint divide exceptions if the cputime is too large.
On a machine that collected 49.7 days worth of idle time reading
from /proc/stat will generate oopses like this:

Kernel BUG at 001b0c92 [verbose debug info unavailable]
