Removing LLVM objtool warning filter

Removing LLVM objtool warning filter

[Nathan Chancellor]

Hi Philip and other LKP folks,

At some point, I believe there was a filter set up so that reports of
objtool warnings that appear in clang builds were sent only to our
mailing list (llvm@lists.linux.dev) for triage. At this point, we
believe it is best to treat those reports like other objtool reports and
send them to the author of the change that introduced the warning with
our list on CC in case people think it is a compiler bug or need further
help understanding what is going on. Is that possible?

Cheers,
Nathan

Got it Nathan, I will update the bot to send out this warning to author
and cc llvm list, same as other warnings from clang.

Just to confirm, is it applied to all clang version or only latest one
like clang 19/20?

Thanks

Thanks a lot!

Let's do all clang versions and see how noisy it is. If we need to scale
it back to just the latest, we can definitely do so.
