Hi,
This patchset includes some of the least controversial changes that were needed as part of the arm64 port [1].
It consist mostly of small fixes or lifting some limitations to make it easier to support a new architecture in objtool. Of course, these will not be the only required changes, but these are the ones I hope make enough sense to be merged separately from the rest of arm64 port series.
The patches should apply cleanly on linux-tip/master tree.

Thanks,
