Kefeng Wang 80bc1e5d9e asm-generic: Add memory barrier dma_mb() 
[ Upstream commit ed59dfd950 ]

The memory barrier dma_mb() is introduced by commit a76a37777f
("iommu/arm-smmu-v3: Ensure queue is read after updating prod pointer"),
which is used to ensure that prior (both reads and writes) accesses
to memory by a CPU are ordered w.r.t. a subsequent MMIO write.
