Main thing is we add the new page-based iomem memcpy util to TTM, and for some speed the copy-from-wc-x86-only prefetching memcpy to core drm. Note that the legacy memcpy path is largely untested. Perhaps can give it some testing on vmwgfx. A bugfix and some minor optimization for the ttm_bo_pipeline_gutting() idle case Finally allow the frequently-pinning i915 driver to block swapping of pinned memory that is still on the LRU. If OK, I'd like to include these as a part of the i915 series.
