Yeah, this is 100% technically correct way of moving things. The problem is that driver maintainers are usually not quick taking this type of changes. In my experience, if we merge #1 only, we'll end up with just another flavor of HIWORD_UPDATE(), maybe adopted by a couple of drivers. This is exactly opposite to the original goal of the series: nice and almost complete consolidation of scattered HIWORD_UPDATE() versions. So far, there's the only conflict with the others, and Andy said he's OK to hold his series. I would prefer to have all those patches in bitmap-for-next for a while. If there will be more conflicts, then yeah, I'll follow your route. Otherwise, let's keep things as they are, and encourage developers to test their patches against linux-next, as they normally should. Thanks, Yury
