The point I was trying to make before was that I wasn't 100% confident that we need the linker scripts to match in that most of the relevant code is in foo_64.S and not foo.S. But from a very quick grep it does look similar enough that perhaps it was ported over directly enough that we should be doing this with the linker scripts here too. Hopefully throwing this in to -next soon enough will get any problems to fall out quickly if we're wrong. -- Tom
