Christoph Hellwig	faef87723a	dma-noncoherent: add a arch_sync_dma_for_cpu_all hook The MIPS bmips platform needs a global flush when transferring ownership back to the CPU. Add a hook for that to the dma-noncoherent implementation.

Christoph Hellwig	cf65a0f6f6	dma-mapping: move all DMA mapping code to kernel/dma 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.

dma-noncoherent: add a arch_sync_dma_for_cpu_all hook

The MIPS bmips platform needs a global flush when transferring ownership
back to the CPU.  Add a hook for that to the dma-noncoherent
implementation.

dma-mapping: move all DMA mapping code to kernel/dma

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.
