Subject: [PATCH v2 0/3] perf/x86/amd/uncore: Update AMD uncore driver

This patchset updates the AMD uncore driver to support AMD Family17h processors.

First, the current L2 counters are renamed to Last level cache (LLC) counter to 
reflect either L2 or L3 counters depending on the family. Next, the maximum 
number of counters available is increased and the counters per uncore type is 
now based on the family.

Also, in Family17h, the NorthBridge counters are re-purposed as Data Fabric (DF) 
counters. Therefore, this patch exports the pmu name accordingly based on the 
processor family.

v1->v2
* Removed dynamic memory allocation for counters, based on Peter Zijlstra's 
  feedback.

Janakarajan Natarajan (3):
  perf/x86/amd/uncore: Update AMD uncore to rename L2 to LLC
  perf/x86/amd/uncore: Update number of uncore counters
  perf/x86/amd/uncore: Update sysfs attributes for Family17h processors
