No way I'm gonna check arbitrary random branch to find out why you refuse to answer my questions/comments about generic general way to handle source in linux. I really think you need to check powerpc, itanium, amr4, younameit branch If your "ported upstream patches" are built in a way they would break ARM build, you evidently messed it up to implement them AFAIK upstream/main is meant to compile on all platforms, with all valid options - at very least there _never_ can be a patch upstream that when "backported" to our local branch would make that branch fail to compile for ARM. Either it been broken before and we better fix it for all upstream stuff, or your backport is flawed. /j
