H A D | spapr.c | 6010818c Wed Jul 02 22:10:05 CDT 2014 Alexey Kardashevskiy <aik@ozlabs.ru> spapr: Split memory nodes to power-of-two blocks Linux kernel expects nodes to have power-of-two size and does WARN_ON if this is not the case: [ 0.041456] WARNING: at drivers/base/memory.c:115 which is: === /* Validate blk_sz is a power of 2 and not less than section size */ if ((block_sz & (block_sz - 1)) || (block_sz < MIN_MEMORY_BLOCK_SIZE)) { WARN_ON(1); block_sz = MIN_MEMORY_BLOCK_SIZE; } === This splits memory nodes into set of smaller blocks with a size which is a power of two. This makes sure the start address of every node is aligned to the node size.
