Subject[PATCH v4 0/5] Add support for the ARMv8.2 Statistical Profiling Extension
Date
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
