I can confirm I saw 4 CPUs online as soon as I had merged renesas-devel containing the above change into my tree (which was based on renesas-drivers-2015-12-08-v4.4-rc4 at that time). I was surprised to see it was that simple to enable the 3 other cores ;-) Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
