Name	Describe
dma_get_sgtable_attrs	The whole dma_get_sgtable() idea is fundamentally unsafe - it seems* that the intention is to allow exporting memory allocated via the* coherent DMA APIs through the dma_buf API, which only accepts a* scattertable. This presents a couple of problems:* 1
dma_can_mmap	dma_can_mmap - check if a given device supports dma_mmap_*@dev: device to check Returns %true if @dev supports dma_mmap_coherent() and dma_mmap_attrs() to* map DMA allocations to userspace.
dma_mmap_attrs	dma_mmap_attrs - map a coherent DMA allocation into user space@dev: valid struct device pointer, or NULL for ISA and EISA-like devices@vma: vm_area_struct describing requested user mapping*@cpu_addr: kernel CPU-view address returned from
