| |
Hi Linus,
I have another mixed bag of ARM-related perf patches here. It's about 25% CPU and 75% interconnect, but with drivers/bus/ languishing without an obvious maintainer or tree, Olof and I agreed to keep all of these PMU patches together. I suspect a whole load of code from drivers/bus/arm-* can be moved under drivers/perf/, so that's on the radar for the future.
In the meantime, please pull. Headlines in the tag.
