This may seem like a no-op change, however it shrinks down the Kernel by a bit: .text -432 .unmap_after_init -60 .data -480 .debug_info -673 .debug_aranges 8 .debug_ranges -232 .debug_line -558 .debug_str -308 .debug_frame -40 With '= default', the compiler can do more inlining, hence the savings. I intentionally omitted some opportunities for '= default', because they would increase the Kernel size.
