Greeting,

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

commit: f0ff2447b8613b883f41ae845b6cc7540d6e5f71 ("selftests/sgx: Add a new kselftest: Unclobbered_vdso_oversubscribed")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git x86/sgx

in testcase: kernel-selftests
version: kernel-selftests-x86_64-99d09ee9-1_20211206
with following parameters:

	group: sgx
	ucode: 0xde

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.
