The following kernel crash reported on arm64 hikey device running stable-rc 5.4.114-rc1 kernel and testing LTP thp04 test case.

Reported-by: Naresh Kamboju naresh.kamboju@linaro.org

I have tried to reproduce this crash but was not successful after multiple attempts. Could not bisect this problem because it is not reproducible.

step to reproduce: ------------------------- - Boot 5.4.114-rc1 kernel on arm64 hikey device. - run ltp cve test case - cd /opt/ltp - ./runltp -f cve - ./runltp -s thp04
