Hi all,

This is the sixth posting of the patches previously posted here:

  rfcv1: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/476450.html
  rfcv2: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/479387.html
     v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/483684.html
     v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-April/499938.html
     v3: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-May/507132.html

The main change since v3 is that I have reworked and fixed the CPU hotplug
and notifier bits, in light of review comments from tglx.

The architecture documentation is available here:

Kim, do you have any version of the userspace side that we could look
at?

For review, it would be really helpful to have something that can poke
the PMU, even if it's incomplete or lacking polish.

Thanks,
Mark.
