Thanks! We only need the C/faq.page, translators will take care of
adding the page to their respective translations. I've modified (and
pushed) the patch to take care of this.

One thing we did when revamping stuff last year was to make the "data
sources" modular. So we can add tracing, Mesa GPU counters, network
statistics, GTK frame clock information, etc without effecting the
sampling profiler.

Coincidentally, if I manage to find time to merge the patches, this is
how we'll gain support for profiling SpiderMonkey-based JavaScript (via
GJS).
