- Query heap functionality belongs to nvmap_alloc unit, as heap is managed by it. Hence move the function to query the heap to nvmap_alloc unit. - Move nvmap_get_user_pages function to nvmap_alloc unit as it is relevant for nvmap_alloc unit. - Move nvmap_dma_alloc_attrs/free_attrs functions to nvmap_alloc unit as they are more relevant for nvmap_alloc unit. - Move dma_coherent_mem_replica, nvmap_carveout_node structs to nvmap_alloc unit. - Cleanup unused macros from nvmap_priv.h JIRA TMM-5694 Change-Id: I8884831771443de7db0e95c3b2dfc43c03f7c48e Signed-off-by: Ketan Patil <ketanp@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3214196 GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com>
