Subject: dma-mapping: clear harmful GFP_* flags in common code

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:
