Since the cacheinfo code is never informed about this, it # never drops its references to the source system's cache nodes, causing # it to wind up in an inconsistent state resulting in warnings and oopses # as soon as CPU online/offline occurs after the migration, e.g. # # cache for /cpus/l3-cache@3113(Unified) refers to cache for /cpus/l2-cache@200d(Unified) # WARNING: CPU: 15 PID: 86 at arch/powerpc/kernel/cacheinfo.c:176 release_cache+0x1bc/0x1d0 # [...] # NIP release_cache+0x1bc/0x1d0 # LR release_cache+0x1b8/0x1d0 # Call Trace: # release_cache+0x1b8/0x1d0 (unreliable) # cacheinfo_cpu_offline+0x1c4/0x2c0 # unregister_cpu_online+0x1b8/0x260 # cpuhp_invoke_callback+0x114/0xf40 # cpuhp_thread_fun+0x270/0x310 # smpboot_thread_fn+0x2c8/0x390 # kthread+0x1b8/0x1c0 # ret_from_kernel_thread+0x5c/0x68 # # Using device tree notifiers won't work since we want to rebuild the # hierarchy only after all the removals and additions have occurred and # the device tree is in a consistent state.
