Subject[PATCH 0/5] Fix Arm system PMU hotplug issues
Hi all,

Following the report of a preemption-related bug in arm-cci, it turns
out there's a fair bit of cleaning up to do in this area. I've started
here with the Arm drivers that I'm fairly familiar with - I suspect the
hisi/qcom/xgene ones suffer from similar issues, but it's going to take
me a while longer to figure them out in detail.


Robin Murphy (5):
perf/arm-cci: Fix CPU hotplug race avoidance
cpu/hotplug: Export __cpuhp_state_add_instance_cpuslocked()
perf/arm-ccn: Fix CPU hotplug race avoidance
cpu/hotplug: Add locked variant of cpuhp_state_add_instance()
perf/arm_dsu: Fix CPU hotplug races
