All logs I analyze are from the linux-next build service at http://kisskb.ellerman.id.au/kisskb/matrix/. I think you can reproduce moft the warnings using the most recent toolchains at https://www.kernel.org/pub/tools/crosstool/files/bin/ Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@xxxxxxxxxxxxxx In personal conversations with technical people, I call myself a hacker.
