Taken into the tile tree.
I thank you for caring, but may I ask you to drop this again?
The reasons are twofold:
1.) It isn't clear yet whether this series is worth it and will be accepted at all (hence the "RFC" tag). This patch by itself would not make any sense.
2.) The patches in this series depend heavily on each other. So I'd personally prefer if those more or less trivial changes to arch/ could be taken through the same tree as the rest, i.e. through the timers/core tree. I have no idea whether this is feasible and perhaps I'll have to get back to you. But for now, getting this patch removed from your tree would certainly simplify things a lot for me...
Thanks and sorry for the inconvenience,
Nicolai Stange
