Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

dma-mapping: cosolidate dma_mapping_error Currently there are three valid implementations of dma_mapping_error: (1) call ->mapping_error (2) check for a hardcoded error code (3) always return 0 This patch provides a common implementation that calls ->mapping_error if present, then checks for DMA_ERROR_CODE if defined or otherwise returns 0.

sh: declared coherent memory support V2 This patch adds declared coherent memory support to the sh architecture. All functions are based on the x86 implementation. Header files are adjusted to use the new functions instead of the former consistent_alloc() code. This version includes the few changes what were included in the fix patch together with modifications based on feedback from Paul.

sh: Add dma-mapping support for dma_alloc/free_coherent() overrides. This moves the current dma_alloc/free_coherent() calls to a generic variant and plugs them in for the nommu default. Other variants can override the defaults in the dma mapping ops directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
