Subject: [PATCH v2 0/4] dma-mapping: Define dma_{alloc,free}_attrs() for all archs

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(). 

As I don't have hardware for any of these systems, the patches are only
compile-tested where I could (arm64, s390) and untested for the archs
where I couldn't find a readily available prebuilt cross-compiler (c6x, parisc).

Changes from v1
---------------

arm64, s390:
 * Since these archs are using dma_ops, pass appropirate value for attrs to 
   dma_ops->alloc().
 * Indicate that these patches are compile teseted only (I don't have hardware)

c6x, parisc:
 * Indicate that these patches are untested (I don't have cross compilers)

Cheers,
Damian
