[Crash-utility] One more change for crash

Hi Dave, I am playing with "crash" on my machine with it fails with CONFIG_SPARSE_MEM. It looks like "node_mem_map" doesn't exist for SPARSE_MEM :( crash: invalid structure member offset: pglist_data_node_mem_map FILE: memory.c LINE: 10053 FUNCTION: dump_memory_nodes() [./crash] error trace: 100afe98 => 100d12f4 => 100d01cc => 10142f64 10142f64: .OFFSET_verify+140 100d01cc: .dump_memory_nodes+520 100d12f4: .node_table_init+492 100afe98: .vm_init+7948 Thanks, Badari typedef struct pglist_data { struct zone node_zones[MAX_NR_ZONES]; struct zonelist node_zonelists[GFP_ZONETYPES]; int nr_zones; #ifdef CONFIG_FLAT_NODE_MEM_MAP struct page *node_mem_map; #endif struct bootmem_data *bdata;
