Just a quick question: is your MIPS build fix going to be merged and sent to Linus? I can apply it too, and send it to Linus later today, together with a few other sched.h header related build fixes. Assuming it's all properly tested - my limited MIPS defconfig builds worked fine - but MIPS has a lot of build variations. Either way is fine to me. Thanks, Ingo
