I am not entirely convinced we need this for the upcoming release. My concern is that this patch set makes a lot of changes. OK, they are mostly limited to the IEEE 1275 stuff but... Anyway, quick glance through the patches revealed that most of them missing explanation why they are really needed. At least... Please fix these things...
