It uses ttm's pool allocator to allocate volatile pages in place of the old code which rolled its own via alloc_pages. This is continuing progress to align all backends on using ttm. v2: - commit message improvements to add detail - fix i915_ttm_shrink to purge !is_shmem volatile buffers - limit ttm pool allocator to using dma32 on i965G[M] - fix mman selftest to always use smem buffers - create new internal memory region - make internal backend allocate from internal region - Fixed various issues with tests and i915 ttm usage as a result of supporting regions other than lmem via ttm. v4: - limit i915 ttm default cache_level selection to only trust v4: - limit i915 ttm default cache_level selection to only trust HAS_SNOOP on DGFX.
