Linus Torvalds 3572597ca8 memblock: fix validation of NUMA coverage
To check for unset node ID for a range memblock_validate_numa_coverage()
 was checking for NUMA_NO_NODE, but x86 used MAX_NUMNODES when no node ID
 was specified by buggy firmware.
 
 Update memblock to substitute MAX_NUMNODES with NUMA_NO_NODE in
 memblock_set_node() and use NUMA_NO_NODE in x86::numa_init().
