Subject: [PATCH v2 0/6] Add support for the ARMv8.2 Statistical Profiling Extension

Hi all,

This is the fourth 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

Changes since v1 include:

  * Rebased onto new perf_aux_output_flag API (in -next via -tip and included here)
  * Fixed allocation of COLLISION flag
  * Fixed buffer draining in IRQ handler
  * Rebased onto v4.11-rc5

The architecture documentation is now 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
