[PATCH] cputime: microsecond based cputime for s390
This patch adds the architecture magic to replace the jiffies based cputime
with microsecond based cputime and it adds code to calculate involuntary
wait time. With this patch the numbers reported by top and ps when running
on LPAR or z/VM are finally not junk anymore.
