* Documentation: DMA-API-HOWTO.txt: rename ARCH_KMALLOC_MINALIGN to ↵FUJITA Tomonori2010-08-141-3/+3
| | | | | | | | | | | | | ARCH_DMA_MINALIGN ARCH_KMALLOC_MINALIGN was renamed to ARCH_DMA_MINALIGN (the commit a6eb9fe105d5de0053b261148cee56c94b4720ca). ARCH_DMA_MINALIGN must be defined instead of ARCH_KMALLOC_MINALIGN to ensure that kmalloc'ed buffer is DMA-safe.

* Documentation: move the error handling to the better place in DMA-API-HOWTOFUJITA Tomonori2010-05-271-30/+30
| | | | | | | | | Handing DMA mapping errors is essential. Let's put it in the more appropriate place rather than the end of the doc.

| | | | | | | | | | Now we have <asm-generic/scatterlist.h>. Architectures should use it instead of inventing the own scatterlist struct. Let's update the description.
