swiotlb: Use is_swiotlb_force_bounce for swiotlb data bouncing

2021-07-14T00:04:43Z

Propagate the swiotlb_force into io_tlb_default_mem->force_bounce and use it to determine whether to bounce the data or not. This will be useful later to allow for different pools.

dma-mapping: move large parts of to kernel/dma

2020-10-06T05:07:06Z

Most of the dma_direct symbols should only be used by direct.c and mapping.c, so move them to kernel/dma. In fact more of dma-direct.h should eventually move, but that will require more coordination with other subsystems. Signed-off-by: Christoph Hellwig
