I've spent some time going over the conversion but can't really pinpoint it. I have three little patches that switch parts of the code to the generic version. This is on top of the last good commmit (977706f9755d2d697aa6f45b4f9f0e07516efeda). Can you check with whіch one things stop working? --Qxx1br4bt0+wmkIi Content-Type: text/x-patch; charset=us-ascii Content-Disposition: attachment; filename="0001-get_required_mask.patch" --Qxx1br4bt0+wmkIi--
