Sanity check that makes sure the nodes cover all memory loops over numa_meminfo to count the pages that have node id assigned by the firmware, then loops again over memblock.memory to find the total amount of memory and in the end checks that the difference between the total memory and memory that covered by nodes is less than some threshold. Worse, the loop over numa_meminfo calls __absent_pages_in_range() that also partially traverses memblock.memory. It's much simpler and more efficient to have a single traversal of memblock.memory that verifies that amount of memory not covered by nodes is less than a threshold. Introduce memblock_validate_numa_coverage() that does exactly that and use it instead of numa_meminfo_cover_memory().
