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

Fine, but it matches what current code is doing.  Since that
MIPS_LIGHTWEIGHT_SYNC patch didn't go into linux-next yet, do
you see a problem reworking it on top of this patchset?
