NOTE:
Following kernel deadlock / rcu warnings noticed while booting
on arm64 Rpi4 and db401 booting with kselftests merge configs builds.
Kernel is built with selftests/*/configs merge.
FYI,
After this kernel warning the system is stable and ran selftests and got passed.
Build and config details provided at the bottom of this email.
