When I've submitted my last patchset titled "efi/runtime-wrappers: bound
the wait for EFI runtime service calls", I've got two reports

1) efi_rts_park_worker() loops forever and never returns, but wasn't
marked __noreturn, so objtool warns about the unreachable code after
the call.

2) efi_runtime_lock_owner is optimised away under CONFIG_BUG=n, leaving a
dangling debug-info reference that breaks the link.

Patch 1 fixes the objtool warning; patch 2 fixes the link error.
