numa_nodes[] doesn't carry any information which isn't present in numa_meminfo. Each entry is simply min/max range of all the memblks for the node. This is not only redundant but also inaccurate when memblks for different nodes interleave - for example, find_node_by_addr() can return the wrong nodeid. Kill numa_nodes[] and always use numa_meminfo instead. * nodes_cover_memory() is renamed to numa_meminfo_cover_memory() and now operations on numa_meminfo and returns bool. * setup_node_bootmem() needs min/max range. Compute the range on the fly. setup_node_bootmem() invocation is restructured to use outer loop instead of hardcoding the double invocations. * find_node_by_addr() now operates on numa_meminfo. * setup_physnodes() builds physnodes[] from memblks. This will go away when emulation code is updated to use struct numa_meminfo. This patch also makes the following misc changes. * Clearing of nodes_add[] clearing is converted to memset(). * numa_add_memblk() in amd_numa_init() is moved down a bit for consistency.
