Summary
perf: hisi: Fix use-after-free when register pmu fails
Details

In the Linux kernel, the following vulnerability has been resolved:

perf: hisi: Fix use-after-free when register pmu fails

When we fail to register the uncore pmu, the pmu context may not been allocated. The error handing will call cpuhpstateremove_instance() to call uncore pmu offline callback, which migrate the pmu context. Since that's liable to lead to some kind of use-after-free.

Use cpuhpstateremoveinstancenocalls() instead of cpuhpstateremove_instance() so that the notifiers don't execute after the PMU device has been failed to register.
