Nice! I was wanting to do that for a long time...
I think the change is good. But I don't want to maintain this whopper
out-of-tree for two months! If we want to do this, we should just smash it
in and grit our teeth.
Yes, lets drop it in while we still not reached rc1.

Good riddance... Athough I would not remove input_regs() just yet but
just redefine it to an empty inline and mark it as depreciated so we
won't break all out-of-tree input drivers right away. Removal of
input_regs() from in-tree drivers could be done by separate patch as
well, once main changes are in.
