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.

Why is the TEMP in the subject line. From patch it doesn't be
temporary version. Can you please clarify that ?

Oops, that was a mistake. Reposted by correcting it.
