Subject: [x86/iopl]  32e1ae626f: kernel-selftests.x86.iopl_64.fail



Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: 32e1ae626f295152d1fc9a3375214133cbe62878 ("x86/iopl: Fake iopl(3) CLI/STI usage")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master


in testcase: kernel-selftests
version: kernel-selftests-x86_64-c8c9111a-1_20210929
with following parameters:

	group: x86
	ucode: 0xe2

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


on test machine: 4 threads Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz with 32G memory

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):




If you fix the issue, kindly add following tag

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
