Yes, sorry. I didn't notice it was already applied.

As I said, I do not really agree with this change,
arch_uprobe_analyze_insn() shouldn't use addr/vaddr.

However this is minor, we can change this later. And this code needs
more changes anyway.

I'll rebase this series on top of your "1/2" and resend.
