This adds the mmap and mmap2 events to the CTF trace obtained from perf
data.
These events will allow CTF trace visualization tools like Trace Compass
to automatically resolve the symbols of the callchain to the
corresponding function or origin library.
To include those events, one needs to convert with the --all option.
Here follows an output of babeltrace:
$ sudo perf data convert --all --to-ctf myctftrace
$ babeltrace ./myctftrace

"/usr/lib/ld-2.25.so" }
