memblock_steal tries to reserve physical memory during boot. When the requested size is not aligned on the section size then, the remaining memory available for lowmem becomes unaligned on the section boundary. There is a issue with this, which is discussed in the thread below. https://lkml.org/lkml/2012/6/28/112 The final conclusion from the thread seems to be align the memblock_steal calls on the SECTION boundary.
