Hi Olof, Kevin,

Please can you pull the following perf update for 3.12? I was hoping to have
some unwinding improvements too, but I've not had a chance to complete that
work, so it's just the single patch from Punit to add support for the PMU
driver on the CCI.

Apologies for sending this post -rc5, but I've been travelling for the past
week and had some issues testing the driver myself. If you're snowed under,
feel free to queue this for 3.13 instead.

Cheers,

Will

I'd like to see a reviewed-by or acked-by from a DT maintainer before
pulling this.

That's fair enough; they've been quiet on the iterations of this patch so
far. However, it looks like a conversation has kicked off on the back of
this pull request:

http://lists.infradead.org/pipermail/linux-arm-kernel/2013-August/192192.html

so I'll wait for that to settle down, then I'll send you another pull (which
I suspect you will want to delay until 3.13).

Cheers,

Will
