I don't think that's a good idea. It would recreate all the 
problems oprofile has with out of date event lists. Already
proven to not work well.

I have doubts a gitweb server is a good way to distribute potentially
high volume / high access data.

However getting a more neutral space is fine.

It would be fine to put it elsewhere on kernel.org.
I can ask for a space.

Otherwise I will just remove the auto URL from the tool, 
so the perf project does not need to endorse any particular
event lists.

Let me know what you prefer. I'll assume the "remove the URL"
variant is the default option.
