Subject: [selftests] fad41fa058: kernel-selftests.kvm.make_fail
Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: fad41fa05876489d76b884c83014b80731e0f60f ("[PATCH 6/6] selftests: kvm: test enforcement of paravirtual cpuid features")
url: https://github.com/0day-ci/linux/commits/Oliver-Upton/Some-fixes-and-a-test-for-KVM_CAP_ENFORCE_PV_CPUID/20201028-095033
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git ed8780e3f2ecc82645342d070c6b4e530532e680
in testcase: kernel-selftests
version: kernel-selftests-x86_64-b5a583fb-1_20201015
with following parameters:
group: kselftests-kvm
ucode: 0xdc
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
