Subject: [PATCH 0/3] objtool: Extend CFA updating/checking

Hi,

The following patches are the result of limitation found on the CFA
management code when trying to validate arm64 frames. I tried to keep
things simple and not contradict current CFA management logic nor
introduce too many corner cases.

The patches apply on top of the cleanup series[1] I sent previously.

Thanks,

Julien
