I think this change is buggy.

What I want in a changelog is: "We're copying data that's little endian from (some place) to where ever and then we (whatever) do math using the variable so it needs to be CPU endian. Presumably this wasn't caught in testing because it was only used on x86 or other little endian systems." In this case we're copying little endian data and then sending it directly back to some place which requires little endian data so converting it is a bug. regards, dan carpenter
