since you use TTM I don't think that selecting DRM_GEM_CMA_HELPER and
DRM_KMS_CMA_HELPER
help you lot here.
You could add configuration flags step by step in following patches
that will make you needs more clear (that also true for #include)
will delete them, thanks.

cma_helpers look useless since you use TTM, no ?
I add TTM just in this version, and forgot to clean these
cma relevant code, will fix in next version. Thanks.
