back to the CPU.  Add a hook for that to the dma-noncoherent

dma-mapping: move all DMA mapping code to kernel/dma 2018-06-14T06:50:37+00:00 Christoph Hellwig hch@lst.de 2018-06-12T17:01:45+00:00 cf65a0f6f6ff7631ba0ac0513a14ca5b65320d80 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.
