Subject: [PATCH v2 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].

I'm resending these rebase on top of linux-tip/core/objtool, following
the addition of Peter's patches [2]

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.

Changes since v1[3]:
- Really just rebased things

Thanks,
