sh: use generic dma_noncoherent_ops (2018-08-02 13:54:20 +0200)

----------------------------------------------------------------
dma-mapping updates for 4.19

- a series from Robin to fix bus imposed dma limits by adding a separate
mask for them to struct device instead of trying to squeeze a second
meaning out of the existing dma mask as we did before. This has ACKs
from the various other subsystems touched
- a small swiotlb cleanup from Kees (acked by Konrad)
- conversion of nios2 and sh to the new generic dma-noncoherent code.
Various other architecture conversions will come through the
architectures maintainers trees.

----------------------------------------------------------------
Christoph Hellwig (6):
nios2: use generic dma_noncoherent_ops
sh: simplify get_arch_dma_ops
sh: introduce a sh_cacheop_vaddr helper
sh: use dma_direct_ops for the CONFIG_DMA_COHERENT case
sh: split arch/sh/mm/consistent.c
sh: use generic dma_noncoherent_ops

Kees Cook (1):
swiotlb: clean up reporting

Robin Murphy (9):
dma-mapping: relax warning for per-device areas
of/platform: Initialise default DMA masks
ACPI/IORT: Support address size limit for root complexes
dma-mapping: Generalise dma_32bit_limit flag
ACPI/IORT: Set bus DMA mask as appropriate
of/device: Set bus DMA mask as appropriate
iommu/dma: Respect bus DMA limit for IOVAs
ACPI/IORT: Don't set default coherent DMA mask
OF: Don't set default coherent DMA mask
