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

Thanks for submitting this! My apologies for the trouble!

We already have a similar patch queued here: https://cgit.freedesktop.org/drm/drm-misc/commit/?h=drm-misc-next-fixes&... so hopefully that will land upstream soon.

thanks again! -john
