Results from Linaro’s test farm.
No regressions on arm64, arm, x86_64, and i386.

Tested-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx>

NOTE:
The following kernel warning was noticed while booting qemu-arm64
with these configs enabled on stable rc 6.4.5-rc1.

CONFIG_ARM64_64K_PAGES=y
CONFIG_KFENCE=y

This crash is not easily reproducible.
