v7: Rebase to 4.8rc3 Remove cpu affinity sysfs entry. While providing a CPU mask for ARMv8 PMU's is really helpful in big/little environments, reworking the PMU code to support the cpumask attribute for !arm64 PMUs is out of the scope of this patch set. Fix CPU miscount problem where an alloc failure followed by successfully allocating the structure can result in under counting the CPUs associated with the PMU. This bug was created in v6 with the conversion to a linked list. Remove initial platform device creation code by Mark Salter, and re-squash multiple platform device creation code together with helper routines. Other minor tweakage. v6: Added cpu affinity sysfs entry Converted pmu_types array, to linked list Restrict use of the armv8_pmu_probe_table to ACPI systems Rename MADT parsing routines in smp.c Convert sysfs PMU name to use index rather than partnum Remove pr_devel statements Other Minor cleanups Add Partial Ack-by Will Deacon v5: Remove list of CPU types for ACPI systems. We now match a generic event list, and use the PMCIED[01] to select events which exist on the given PMU. This avoids the need to update the kernel every time a new CPU is released. Update the maintainers list to include the new file. v4: Correct build issues with ARM (!ARM64) kernels. Add ThunderX to list of PMU types. v3: Enable ARM performance monitoring units on ACPI/arm64 machines. This patch expands and reworks the patches published by Mark Salter in order to clean up a few of the previous review comments, as well as add support for newer CPUs and big/little configurations.
