No, sorry for confusion, I meant another thing... But please forget. If we rely on
verify_opcode() I no longer think it would be more clean to move this logic into
install/remove_breakpoint.

However, I still think it would be better to avoid uprobe exporting and modifying
set_swbp/set_orig_insn. May be we can simply kill both set_swbp() and set_orig_insn(),
I'll re-check...

Oleg.
