Subject: [PATCH 00/10] Objtool updates for easier portability

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,

Julien
