[RFC/PATCH 0/4] dma-mapping: Define dma_{alloc, free}_attrs() for all archs

[Damian Hobson-Garcia]

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
