Subject: [GIT PULL] dma-mapping updates for 5.4
Hi Linus,
please pull the dma-mapping updates for 5.4.
In addition to the usual Kconfig conflics where you just want to keep
both edits there are a few more interesting merge issues this time:
- most importanly powerpc and microblaze add new callers of
dma_atomic_pool_init, while this tree marks the function static
and calls it from a common postcore_initcall(). The trivial
functions added in powerpc and microblaze adding the calls
need to be removed for the code to compile. This will not show up
as a merge conflict and needs to be dealt with manually!
- the csky tree has edits close to edits from this tree in
arch/csky/mm/dma-mapping.c, keep both edits as there are no
functional conflicts.
- for ia64 keep the removal of arch/ia64/sn/pci/pci_dma.c from the
ia64 tree. The ia64 tree moves sba_dma_ops around a bit. Keep
the move and the wiring up of ->mmap and ->get_sgtable from this
tree.
- the -mm tree adds a new compound_nr helper that some of the Xen
code removed in this pull request removes. Keep the removal from
this tree.
- the block tree adds a new helper next to the new block helpers from
this tree, keep both
- the arm64 tree removes a __KERNEL__ ifdef from
arch/arm64/include/asm/dma-mapping.h, which is removed in this tree.
Keep the removal.

mmc: renesas_sdhi_internal_dmac: Add MMC_CAP2_MERGE_CAPABLE (2019-09-12 13:14:09 +0100)
----------------------------------------------------------------
dma-mapping updates for 5.4:
- add dma-mapping and block layer helpers to take care of IOMMU
merging for mmc plus subsequent fixups (Yoshihiro Shimoda)
- rework handling of the pgprot bits for remapping (me)
- take care of the dma direct infrastructure for swiotlb-xen (me)
- improve the dma noncoherent remapping infrastructure (me)
- better defaults for ->mmap, ->get_sgtable and ->get_required_mask (me)
- cleanup mmaping of coherent DMA allocations (me)
- various misc cleanups (Andy Shevchenko, me)
