As a matter of fact, this is present in kernels earlier than 3.17 but in
the 3.17 the code has been moved from drivers/base/dma-contiguous.c to
mm/cma.c so this might require separate stable patch.

That could be done, but I'm not sure if it's really worth it. The bug only 
occurs when the CMA zone activation fails. I've ran into that case due to a 
bug introduced in v3.18-rc1, but this shouldn't be the case for older kernel 
versions.

Fair enough.
