I think I already sent all need patches to ML. But I did not check if
you merged them or not. I did not get any new comments for them for a
while and right now I do not have time for looking at it again.

I'm against removing board-rx51*.c files before /proc/cpuinfo and
/proc/atags will be available also for DT booted machine...

Plus there were some other regression for DT booted N900 (not only /proc
files), but I do not remember them now. I sent more emails where I
wrote it. Maybe it is fixed, maybe not, just search into archive for my
emails.

I can try to find some time at the weekend (this or next) to test
4.1-rc* kernel on N900 and report what is working...

Thanks!
