| 2018-06-14 | dma-mapping: move all DMA mapping code to kernel/dma | Christoph Hellwig | |
| Currently the code is split over various files with dma- prefixes in the lib/ and drives/base directories, and the number of files keeps growing. Move them into a single directory to keep the code together and remove the file name prefixes. To match the irq infrastructure this directory is placed under the kernel/ directory.

| 2018-05-19 | dma-mapping: provide a generic dma-noncoherent implementation | Christoph Hellwig | |
| Add a new dma_map_ops implementation that uses dma-direct for the address mapping of streaming mappings, and which requires arch-specific implemenations of coherent allocate/free. Architectures have to provide flushing helpers to ownership trasnfers to the device and/or CPU, and can provide optional implementations of the coherent mmap functionality, and the cache_flush routines for non-coherent long term allocations.
