Not used.\n No NUMA configuration found\n Faking a node at [mem 0x0000000000000000-0x000000027fffffff]\n\nwas seen in the log directly after the message quoted above), because of\nmemblock_validate_numa_coverage() checking for NUMA_NO_NODE (only). This\nin turn led to memblock_alloc_range_nid()'s warning about MAX_NUMNODES\ntriggering, followed by a NULL deref in memmap_init() when trying to\naccess node 64's (NODE_SHIFT=6) node data.\n\nTo compensate said change, make memblock_set_node() warn on and adjust\na passed in value of MAX_NUMNODES, just like various other functions\nalready do.\n\ud83d\udccf Published: 2024-07-12T12:25:00.175Z\n\ud83d\udccf Modified: 2025-01-17T13:26:57.833Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/4ddb7f966f3d06fcf1ba5ee298af6714b593584b\n2. https://git.kernel.org/stable/c/22f742b8f738918f683198a18ec3c691acda14c4\n3. https://git.kernel.org/stable/c/e0eec24e2e199873f43df99ec39773ad3af2bff7", "creation_timestamp": "2025-01-17T13:56:48.000000Z"} 2025-01-17T13:56:48+00:00
