 BUG:sleeping_function_called_from_invalid_context_at_lib/ioremap.c


FYI, we noticed the following commit (built with gcc-6):

commit: b39ab98e2f4728d98973fd1bc531e3c4cbccb21c ("Mark 'ioremap_page_range()' as possibly sleeping")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: unixbench
with following parameters:

	runtime: 300s
	nr_task: 1
	test: pipe
	cpufreq_governor: performance

test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
