Subject: use the generic DMA direct remap code on powerpc
Date: Wed, 14 Aug 2019 15:22:29 +0200 [thread overview]
Message-ID: <20190814132230.31874-1-hch@lst.de> (raw)
Hi powerpc maintainers,
this patch convers powerpc to use the generic dma remapping code
for the uncached coherent allocation on non-coherent CPUs.
Christophe Leroy tested a slightly earlier version on ppc8xx.
Note that I plan to move the need for the arch to call
dma_atomic_pool_init in this cycle, so either this needs to go in
through the dma-mapping tree (or a shared stable branch with it), or
we will need a small manual fixup in linux-next and when Linus merged
the later of the two pull requests.
