+ if possible
+Date: Wed, 29 May 2019 12:43:12 +0200
+
+The dma_required_mask might overestimate the memory size, or might not match
+up with the CMA area placement for other reasons. Get the information about
+CMA area placement directly from CMA where it is available, but keep the
+dma_required_mask as an approximate fallback for architectures where CMA is
