Hi Linus,
please pull dma dma-mapping update below. Note that this includes a lot
of changes to the architecture Kconfig files, which have created quite a
few trivial conflicts in linux-next. In all the cases there is no actual
interaction, just separate additions/removal that are right next to each
other. For nds32 one of these conflicts already exists for 4.17, so
you'll see it straight away.
The following changes since commit 892a0be43edd63e1cd228af3453a064e9e94f08e:
swiotlb: fix inversed DMA_ATTR_NO_WARN test (2018-05-02 14:48:55 +0200)
are available in the git repository at:

dma-direct: don't crash on device without dma_mask (2018-05-31 18:35:36 +0200)
----------------------------------------------------------------
dma-mapping updates for 4.18:
- replaceme the force_dma flag with a dma_configure bus method.
(Nipun Gupta, although one patch is іncorrectly attributed to me
due to a git rebase bug)
- use GFP_DMA32 more agressively in dma-direct. (Takashi Iwai)
- remove PCI_DMA_BUS_IS_PHYS and rely on the dma-mapping API to do the
right thing for bounce buffering.
- move dma-debug initialization to common code, and apply a few cleanups
to the dma-debug code.
- cleanup the Kconfig mess around swiotlb selection
- swiotlb comment fixup (Yisheng Xie)
- a trivial swiotlb fix. (Dan Carpenter)
- support swiotlb on RISC-V. (based on a patch from Palmer Dabbelt)
- add a new generic dma-noncoherent dma_map_ops implementation and use
it for arc, c6x and nds32.
- improve scatterlist validity checking in dma-debug. (Robin Murphy)
- add a struct device quirk to limit the dma-mask to 32-bit due to
bridge/system issues, and switch x86 to use it instead of a local
hack for VIA bridges.
- handle devices without a dma_mask more gracefully in the dma-direct
code.
