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!

[ARM] 3942/1: ARM: comment: consistent_sync should not be called directly /* * Note: Drivers should NOT use this function directly, as it will break * platforms with CONFIG_DMABOUNCE. * Use the driver DMA support - see dma-mapping.h (dma_sync_*) */ Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] Rename consistent_sync() as dma_cache_maint() consistent_sync() is used to handle the cache maintainence issues with DMA operations. Since we've now removed the misuse of this function from the two MTD drivers, rename it to prevent future mis-use. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[PATCH] arm: add comment about dma_supported() ) From: Russell King <rmk+lkml@arm.linux.org.uk> The ARM dma_supported() is rather basic, and I don't think it takes into account everything that it should do (eg, whether the mask agrees with what we'd return for GFP_DMA allocations).

[PATCH] Add struct dev pointer to dma_is_consistent() dma_is_consistent() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_is_consistent to take a struct device pointer as first argument and fix the sole caller to pass it.

[ARM] 3439/2: xsc3: add I/O coherency support Patch from Lennert Buytenhek This patch adds support for the I/O coherent cache available on the xsc3. The approach is to provide a simple API to determine whether the chipset supports coherency by calling arch_is_coherent() and then setting the appropriate system memory PTE and PMD bits. In addition, we call this API on dma_alloc_coherent() and dma_map_single() calls. A generic version exists that will compile out all the coherency-related code that is not needed on the majority of ARM systems. Note that we do not check for coherency in the dma_alloc_writecombine() function as that still requires a special PTE setting. We also don't touch dma_mmap_coherent() as that is a special ARM-only API that is by definition only used on non-coherent system.
