When building cma_heap the following error shows up:

drivers/dma-buf/heaps/cma_heap.c:195:10: error: implicit declaration of function 'vmap'; did you mean 'kmap'? [-Werror=implicit-function-declaration]
195 |  vaddr = vmap(buffer->pages, buffer->pagecount, VM_MAP, PAGE_KERNEL);
    |          ^~~~
    |          kmap

Use this include: linux-next/include/linux/vmalloc.h
