Heiko Carstens 9f88eb4df7 s390/kexec: use node 0 when re-adding crash kernel memory ... When re-adding crash kernel memory within setup_resources() the function memblock_add() is used. That function will add memory by default to node "MAX_NUMNODES" instead of node 0, like the memory detection code does. In case of !NUMA this will trigger this warning when the kernel generates the vmemmap: Usage of MAX_NUMNODES is deprecated. Use NUMA_NO_NODE instead WARNING: CPU: 0 PID: 0 at mm/memblock.c:1261 memblock_virt_alloc_internal+0x76/0x220 CPU: 0 PID: 0 Comm: swapper Not tainted 4.9.0-rc6 #16 Call Trace: [<0000000000d0b2e8>] memblock_virt_alloc_try_nid+0x88/0xc8 [<000000000083c8ea>] __earlyonly_bootmem_alloc.constprop.1+0x42/0x50 [<000000000083e7f4>] vmemmap_populate+0x1ac/0x1e0 [<0000000000840136>] sparse_mem_map_populate+0x46/0x68 [<0000000000d0c59c>] sparse_init+0x184/0x238 [<0000000000cf45f6>] paging_init+0xbe/0xf8 [<0000000000cf1d4a>] setup_arch+0xa02/0xae0 [<0000000000ced75a>] start_kernel+0x72/0x450 [<0000000000100020>] _stext+0x20/0x80 If NUMA is selected numa_setup_memory() will fix the node assignments before the vmemmap will be populated; so this warning will only appear if NUMA is not selected. To fix this simply use memblock_add_node() and re-add crash kernel memory explicitly to node 0.
