This series is a complete re-design of V1 of the QCOM Falkor extensions [1], it introduces a probe table based on the HID of a device nested under the CPU device to allow variant detection and arm_pmu customization. The first patch adds an additional section at the end of each ACPI probe table. This allows probe tables to be sentinel-delimited and better accommodate some APIs that require such tables. The second patch adds the PMUv3 ACPI probe table and plumbing to allow drivers to plug into the ACPI PMUv3 probe sequence. The third patch adds the QCOM Falkor extensions using the new probe table. If this found to be a reasonable extension approach other patches will be added to the series to build on the base QCOM extensions. [1] https://lkml.org/lkml/2017/3/1/540 Changes since V2: - Address V2 comments, which resulted in removing all uses of the PMU lock. Changes since V1: - Redesign as a separate module by adding variant detection support.
