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:

  https://developer.arm.com/products/architecture/a-profile/docs/ddi0586/latest/arm-architecture-reference-manual-supplement-statistical-profiling-extension-for-armv8-a

and there's a high-level overview on this official ARM blog:

  https://community.arm.com/processors/b/blog/posts/statistical-profiling-extension-for-armv8-a

All comments welcome,

Will
