  dma-mapping: postpone cpu addr translation on mmap (2018-04-23 14:44:24 +0200)

----------------------------------------------------------------
A few small dma-mapping fixes for Linux 4.17-rc3:

 - don't loop to try GFP_DMA allocations if ZONE_DMA is not actually
   enabled (regression in 4.16)
 - don't try to do virt_to_page before we know we actuall have a
   valid page in dma_common_mmap
 - a comment fixup related to the above fix
