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!

[ARM] dma: Use sensible DMA parameters for Acorn drivers The hardware supports transfers up to a page boundary per buffer. Currently, we work around that in the DMA code by splitting each buffer up as we run through the scatterlist. Avoid this by telling the block layers about the hardware restriction. Eventually, this will allow us to phase out the splitting code, but not until the old IDE layer allows us to control the value it gives to blk_queue_segment_boundary().
