x86-64, NUMA: Kill numa_nodes[]
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.
