no, i didnt plan to push this towards linux-next - given the broad 
consensus and given the wide spread of the changes.

I wanted to wait with this until the end of the merge window and keep it 
tested and merged up nicely. I.e. zero maintenance overhead to 
subsystems.

i think it's better to just go through the merge window i believe, and 
then do this atomically in one correct and tested step, when all 
subsystem trees are at their minimum size and there's virtually no 
collisions.

Note that this situation is special: this is a patchset that has 
virtually no functionality side-effects, and hence can be done 100% 
correctly, i thought the atomic step was the right approach.

For anything semantically meaningful i too would do the spread-out 
gradual approach (and i'm presently doing that for a number of topics).

But if you'd like to do this the spread-out way then sure, and i will 
drop this tree. ( if you do that then please import the commits from 
tip/core/warn-API, i fixed a couple of of typos in the commit messages 
and did some merging and extensions as well. The tree also passed a fair 
amount of testing meanwhile as well. )

Anyway, your call.
