Not bad. However, exec_test and fork_test are kinda unexpected with such
a high improvement percentage. Happen to have an explanation?

FWIW, if we don't find any serious perf/power regressions with
this patch, I'd say it is worth applying even solely for the code
simplification it brings.

Thanks.
