If you make that change, at least also change the caller of __is_prefetch
As the patch stands it will break the build of fault.c - I suspect you
didn't compile test it.??

Also, addr gets passed in to is_prefetch() from several different
locations before it gets passed on to __is_prefetch() - are you sure it's
correct to just remove the function argument - can you prove that it does
no harm? could it be that the correct fix would be to actually use it for
something instead? I don't know the code enough to be able to answer
that, but I think it's a good question that needs to be answered.

What kernel source is this against? it doesn't seem to apply to my
2.6.10-rc3-bk2 tree here.
