FYI, I've now merged this into the ARM devel tree for the time being so it doesn't get forgotten - which means it'll appear in linux-next at some point if it isn't already there. (Mainly so I don't have to keep on adding the patch.) Once you push it into mainline, I'll drop my copy. ^ permalink raw reply [flat|nested] 12+ messages in thread
