  Contains fixes w.r.t usage of LBR Freeze, Erratum 1452 and a bug in the
CPU offline path where PMU-related registers are reset.

Sandipan Das (3):
  perf/x86/amd/lbr: Use freeze based on availability
  perf/x86/amd/lbr: Discard erroneous branch entries
  perf/x86/amd/core: Avoid register reset when CPU is dead
