On mips dma_rmb, dma_wmb, smp_store_mb, read_barrier_depends, smp_read_barrier_depends, smp_store_release and smp_load_acquire match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead.
This statement doesn't fit MIPS barriers variations. Moreover, there is
a reason to extend that even more specific, at least for
smp_store_release and smp_load_acquire, look into
