This is mainly a pre-check that the core TTM changes for the initial
i915 TTM patch series look reasonably ok.
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.
