Hi all,

After merging the drm tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c: In function 'init_user_pages':
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c:632:3: error: implicit declaration of function 'release_pages'; did you mean 'release_task'? [-Werror=implicit-function-declaration]
   release_pages(mem->user_pages, bo->tbo.ttm->num_pages);
   ^~~~~~~~~~~~~
   release_task

Caused by commit

  5ae0283e831a ("drm/amdgpu: Add userptr support for KFD")

I have applied the following patch for today:
