Btw, could you give me some hints regarding the Blackfin project policy for updating svn://sources.blackfin.uclinux.org/linux-kernel and/or git://sources.blackfin.uclinux.org/git/readonly-mirrors/linux-kernel.git? Is the latter still a pre-mainline staging tree pulling from the former? More specifically, which one shall I pull your changes from? (the blackfin.uclinux.org seems currently unreachable).

That should be ok; I have a single patch and this is fine as long as I am able to rebase it on the next tree; I don't need much linear history here. I will send the arch-dep part of it for inclusion as usual, the rest landing on the bfin_patch/ area IIRC.
