Hello,
May we have
e89f5b370153 ("dma-mapping: Don't clear GFP_ZERO in dma_alloc_attrs")
back-ported to 4.16 kernel as it fixes:
57bf5a8 ("dma-mapping: clear harmful GFP_* flags in common code").
For more info about introduced problem see this thread:
http://lists.infr
Lift the code from x86 so that we behave consistently. In the future we
should probably warn if any of these is set.

Gr{oetje,eeting}s,
