From "[PATCHv11 0/8] Contiguous Memory Allocator"

https://groups.google.com/forum/#!topic/linux.kernel/5JSXa3vxNmA

A few words for these who see CMA for the first time:

   The Contiguous Memory Allocator (CMA) makes it possible for device
   drivers to allocate big contiguous chunks of memory after the system
   has booted.

   The main difference from the similar frameworks is the fact that CMA
   allows to transparently reuse memory region reserved for the big
   chunk allocation as a system memory, so no memory is wasted when no
   big chunk is allocated. Once the alloc request is issued, the
   framework will migrate system pages to create a required big chunk of
   physically contiguous memory.

   For more information you can refer to nice LWN article: 
   http://lwn.net/Articles/447405/ and links to previous versions
   of CMA framework.

   The CMA framework has been initially developed by Michal Nazarewicz
   at Samsung Poland R&D Center. Since version 9, I've taken over the
   development, because Michal has left the company.
