I just sent some series the arm64 objtool support:
- https://lkml.org/lkml/2021/1/20/791
- 
https://lore.kernel.org/linux-arm-kernel/20210120173800.1660730-1-jthierry@redhat.com/T/#t

There are still some things missing, so if you want to investigate a 
more complete state I have a branch:
$ git clone https://github.com/julien-thierry/linux.git -b 
objtoolxarm64-latest

Let me know if there are any questions related to it.

Cheers,
