| 2018-12-20 | dma-mapping: zero memory returned from dma_alloc_* | Christoph Hellwig | |
| If we want to map memory from the DMA allocator to userspace it must be zeroed at allocation time to prevent stale data leaks. We already do this on most common architectures, but some architectures don't do this yet, fix them up, either by passing GFP_ZERO when we use the normal page allocator or doing a manual memset otherwise.

| 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.
