Subject: [PATCH 1/9] perf annotate: Fix annotation_calc_lines()
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.
Fixes: 7d18a824b5e5 ("perf annotate: Toggle full address <-> offset display")
