[kernel test robot <xiaolong.ye@xxxxxxxxx>]

FYI, we noticed the following commit:

commit: f61a8e12b5972879f8decfe059e54c813dc4416b ("x86/time: Initialize 
interrupt mode behind timer init")
url: 
https://github.com/0day-ci/linux/commits/Dou-Liyang/Unify-the-interrupt-delivery-mode-and-do-its-setup-in-advance/20170705-124610


in testcase: will-it-scale
with following parameters:

        nr_task: 50%
        mode: process
        test: writeseek3
        cpufreq_governor: performance

test-description: Will It Scale takes a testcase and runs it from 1 through to 
n parallel copies to see if the testcase will scale. It builds both a process 
and threads based test in order to see any differences between the two.
