Subject: [stable-rc 5.4] thp04: page allocation failure: order:0,
 mode:0x400dc0(GFP_KERNEL_ACCOUNT|__GFP_ZERO), nodemask=(null)

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@...aro.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

Test crash log:
