dma-direct: don't over-decrypt memory (2022-05-23 15:25:40 +0200)
There is a small merge conflict with the (as of now not merged yet) iommu
tree, which removes some code modified in this pull request. The proper
merge resolution is to still remove the modified code.
----------------------------------------------------------------
dma-mapping updates for Linux 5.19
- don't over-decrypt memory (Robin Murphy)
- takes min align mask into account for the swiotlb max mapping size
(Tianyu Lan)
- use GFP_ATOMIC in dma-debug (Mikulas Patocka)
- fix DMA_ATTR_NO_KERNEL_MAPPING on xen/arm (me)
- don't fail on highmem CMA pages in dma_direct_alloc_pages (me)
- cleanup swiotlb initialization and share more code with swiotlb-xen
(me, Stefano Stabellini)
----------------------------------------------------------------
Christoph Hellwig (19):
dma-direct: use is_swiotlb_active in dma_direct_map_page
swiotlb: make swiotlb_exit a no-op if SWIOTLB_FORCE is set
swiotlb: simplify swiotlb_max_segment
swiotlb: rename swiotlb_late_init_with_default_size
MIPS/octeon: use swiotlb_init instead of open coding it
x86: remove the IOMMU table infrastructure
x86: centralize setting SWIOTLB_FORCE when guest memory encryption is enabled
swiotlb: make the swiotlb_init interface more useful
swiotlb: add a SWIOTLB_ANY flag to lift the low memory restriction
swiotlb: pass a gfp_mask argument to swiotlb_init_late
swiotlb: provide swiotlb_init variants that remap the buffer
swiotlb: merge swiotlb-xen initialization into swiotlb
swiotlb: remove swiotlb_init_with_tbl and swiotlb_init_late_with_tbl
x86: remove cruft from <asm/dma-mapping.h>
swiotlb-xen: fix DMA_ATTR_NO_KERNEL_MAPPING on arm
dma-direct: don't fail on highmem CMA pages in dma_direct_alloc_pages
swiotlb: don't panic when the swiotlb buffer can't be allocated
swiotlb: use the right nslabs value in swiotlb_init_remap
swiotlb: use the right nslabs-derived sizes in swiotlb_init_late
Mikulas Patocka (1):
dma-debug: change allocation mode from GFP_NOWAIT to GFP_ATIOMIC
Robin Murphy (1):
dma-direct: don't over-decrypt memory
Stefano Stabellini (1):
arm/xen: don't check for xen_initial_domain() in xen_create_contiguous_region
Tianyu Lan (1):
swiotlb: max mapping size takes min align mask into account
