Subject: [PATCH 0/3] perf, amd: Support for Family 16h L2I Performance Counters

Upcoming AMD Family 16h Processors provide 4 new performance counters
to count L2 related events. Similar to northbridge counters, these new
counters are shared across multiple CPUs that share the same L2 cache.
This patchset adds support for these new counters and enforces sharing
by leveraging the existing sharing logic used for the northbridge
counters.

Jacob Shin (3):
  perf, amd: Further generalize NB event constraints handling logic
  perf, x86: Allow for multiple kfree_on_online pointers
  perf, amd: Enable L2I performance counters on AMD Family 16h
