* dma-mapping: rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGNFUJITA Tomonori2010-08-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto).

* mn10300: set ARCH_KMALLOC_MINALIGNFUJITA Tomonori2010-05-251-0/+2
| | | | | | | | | | | | | | Architectures that handle DMA-non-coherent memory need to set ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the buffer doesn't share a cache with the others.

* Separate out the proc- and unit-specific header directories from the generalDavid Howells2009-04-101-1/+1
| | | | | | | | | | | MN10300 arch headers and place them instead in the same directories as contain the .c files for the processor and unit implementations. This permits the symlinks include/asm/proc and include/asm/unit to be dispensed with. This does, however, require that #include <asm/proc/xxx.h> be converted to #include <proc/xxx.h> and similarly for asm/unit -> unit. Signed-off-by: David Howells <dhowells@redhat.com>
