Subject: [GIT PULL] arm64: perf updates for 4.6
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.
Will
