[ Upstream commit aaf494cf483a1a835c44e942861429b30a00cab0 ]
It should pass a proper address (i.e. suitable for objdump or addr2line) to get_srcline() in order to work correctly. It used to pass an address with map__rip_2objdump() as the second argument but later it's changed to use notes->start. It's ok in normal cases but it can be changed when annotate_opts.full_addr is set. So let's convert the address directly instead of using the notes->start.
Also the last argument is an IP to print symbol offset if requested. So it should pass symbol-relative address.
