I'm guessing CMA means Conventional Memory Area to you. To me it means contiguous memory allocator. Anyway, please define acronyms when you use them, especially in help text. The help text also doesn't really explain where it will find this memory. Would it be possible to provide more direction there? I don't have any useful commentary on the patch itself. I do wonder if you shouldn't move this to the end, as it's hardly an integral part of the patch set.
