Sigh, again new macro without users...
The users are in 01/29 and 04/29, perhaps you missed them.
Using before defining? Cool. :-]
We are currently touching 82 files. I think the patch set is bisectable for non-octeon targets.
If you would like me to move the Kconfig patch to the end, I can do that. That way you wouldn't have any breakage for octeon if you were to only apply a subset of the patches. Other than that, there are currently no plans to restructure this patch set to try to maintain rigorous define before use ordering.
Maybe it's just me, but IMHO first using the macro and then, 15 patches after that, having a patch that just adds that macro, is going against the common sense...
