- Add CBC carveout suport in nvmap. - Chunk size for CBC is 2MB, hence each bit from bitmap for CBC carveout indicate 2MB physically contiguous chunk. - In case of allocation from CBC, first try to allocate the entire chunk in physically contiguous manner, if it's not possible then allocate in chunks of 2MB. All page pointers to these chunks will be stored in nvmap_handle struct. - Modify all other operations like vmap, kmap, mmap as per the above restrictions.
