As I forgot to cc linux-mips on my previous email: I'm planning to queue this for v4.15. Over the weeked I got this bcma patch, but don't know if it's related or not: bcma: Prevent build of PCI host features in module https://patchwork.kernel.org/patch/10161087/ And Guenter's patch is: https://patchwork.kernel.org/patch/10162839/ Which one should I take? Adding also Matt. And Matt also submitted similar patch for ssb: ssb: Prevent build of PCI host features in module https://patchwork.kernel.org/patch/10161131/ -- Kalle Valo
