Most architectures that define CONFIG_HAVE_DMA=y, have implementations for
both dma_alloc_attrs() and dma_free_attrs(). All achitectures that do
not define CONFIG_HAVE_DMA also have both of these definitions provided by
dma-mapping-broken.h.
Provide a default definition for the archs that define CONFIG_HAVE_DMA=y,
but have no implementation for dma_{alloc,free}_attrs() by simply calling
dma_{alloc,free}_coherent() and throwing away the attrs argument.
Damian Hobson-Garcia (4):
Provide default implementation for dma_{alloc,free}_attrs on arm64
Provide default implementation for dma_{alloc,free}_attrs on c6x
Provide default implementation for dma_{alloc,free}_attrs on parisc
Provide default implementation for dma_{alloc,free}_attrs on s390
