Merge tag 'arm64-perf' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 perf updates from Will Deacon:
 "The main addition here is support for Broadcom's Vulcan core using the
  architected ID registers for discovering supported events.

   - Support for the PMU in Broadcom's Vulcan CPU

   - Dynamic event detection using the PMCEIDn_EL0 ID registers"
