Subject: [PATCH 00/12] MIPS: Support I6500 multi-cluster configuration

Taken from Paul Burton MIPS repo with minor changes. Tested with
64r6el_defconfig on Boston board in 2 cluster/2 VPU and 1 cluster/4 VPU
configurations.

Chao-ying Fu (1):
  irqchip: mips-gic: Setup defaults in each cluster

Paul Burton (11):
  MIPS: CPS: Add a couple of multi-cluster utility functions
  MIPS: GIC: Generate redirect block accessors
  irqchip: mips-gic: Introduce gic_with_each_online_cpu()
  irqchip: mips-gic: Support multi-cluster in gic_with_each_online_cpu()
  irqchip: mips-gic: Multi-cluster support
  clocksource: mips-gic-timer: Always use cluster 0 counter as clocksource
  clocksource: mips-gic-timer: Enable counter when CPUs start
  MIPS: pm-cps: Use per-CPU variables as per-CPU, not per-core
  MIPS: CPS: Introduce struct cluster_boot_config
  MIPS: Report cluster in /proc/cpuinfo
  MIPS: CPS: Boot CPUs in secondary clusters
