LLD has the -zbti-report=error argument to check if the BTI note is present when linking. To allow for this to be used when linking the kernel and modules: - Add the BTI note to the remaining assembly files - Mark ptrauth.c as protected by BTI - Disable -zbti-report for vmm hypervisor switching code as it's not used there. The linux64 module doesn't build with the flag as it includes vdso code that doesn't include the note.
