Most architectures that define CONFIG_HAS_DMA=y, have implementations for
both dma_alloc_attrs() and dma_free_attrs(). All achitectures that do
not define CONFIG_HAS_DMA also have both of these definitions provided by
dma-mapping-broken.h.
Provide a default definition for the archs that define CONFIG_HAS_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).
Changes from v2
---------------
Correct commit log. CONFIG_HAVE_DMA should be CONFIG_HAS_DMA.
Remove parisc from the patch series as it has already been merged.
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:
* Indicate that this patch is untested (I don't have a cross compiler)
Cheers,
Damian
