Wtf. More memcorruption smell.

commit dafdf69736d66075836b7bc291584cd0889e7601 (HEAD -> topic/core-for-CI, drm-intel/topic/core-for-CI)

    perf/core: Avoid removing shared pmu_context on unregister
    
    In commit 1fd7e4169954 ("perf/core: Remove perf_cpu_context::unique_pmu"),
    the search for another user of the pmu_cpu_context was removed, and so
    we unconditionally free it during perf_pmu_unregister. This leads to
    random corruption later and a BUG at mm/percpu.c:689.
    
    v2: Check for shared pmu_contexts under the mutex.
    
    Fixes: 1fd7e4169954 ("perf/core: Remove perf_cpu_context::unique_pmu")
