-Subject: [PATCH] dma-direct: unify the dma_capable definitions
-
-commit 130c1ccbf55330b55e82612a6e54eebb82c9d746 upstream.
-
-Currently each architectures that wants to override dma_to_phys and
-phys_to_dma also has to provide dma_capable.  But there isn't really
-any good reason for that.  powerpc and mips just have copies of the
-generic one minus the latests fix, and the arm one was the inspiration
-for said fix, but misses the bus_dma_mask handling.
-Make all architectures use the generic version instead.
