I've no idea why this message was filtered,
but for some reason, my mailer shows it as sucessfully sent,
but it never arrived at LKML...

Hello,

with clang 22.1.4, I get an error in the "LD vmlinux.o" step
(full lto):
"objtool: bad .discard.annotate_insn entry: 609 of type 8"

Same kernel & same config compiles and runs nicely with clang 21.1.8.

I've attached the kernel config to
https://bugzilla.kernel.org/show_bug.cgi?id=221460
