[Bug uprobes/10458] New: uaddr() returns one past current instruction for uprobes

[mjw at redhat dot com]

While writing a testcase for bug #10454 I noticed uaddr() returns one off
results for uprobes. That is, it returns the pc as if it is just after the
breakpoint (int3 trap) instruction.

a) do we consider this a bug?
b) where should this be fixed?
   alternatives are:
   - uprobes setting task_pt_regs REG_IP back just before the callback
   - uaddr just always substracting 1 (probably arch dependent)
