Subject: [kernel/sofirq]  ffce8e6f93:
 BUG:using_smp_processor_id()in_preemptible

FYI, we noticed the following commit (built with gcc-7):

commit: ffce8e6f936e3d879910a76cf8ce6293d78a51e6 ("kernel/sofirq: consolidate common code in __tasklet_schedule() + _hi_")
url: https://github.com/0day-ci/linux/commits/Sebastian-Andrzej-Siewior/kernel-sofirq-consolidate-common-code-in-__tasklet_schedule-_hi_/20180218-010957


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

	test: pthread_mutex1

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.
test-url: https://github.com/antonblanchard/will-it-scale
