This patch series re-work a few i915 functions to use drm_clflush_virt_range instead of calling clflush or clflushopt directly. This will prevent errors when building for non-x86 architectures. v2: s/PAGE_SIZE/sizeof(value) for Re-work intel_write_status_page and added more patches to convert additional clflush/clflushopt to use drm_clflush*. (Michael Cheng) v3: Drop invalidate_csb_entries and directly invoke drm_clflush_virt_ran v4: Remove extra memory barriers v5: s/cache_clflush_range/drm_clflush_virt_range v6: Fix up "Drop invalidate_csb_entries" to use correct parameters. Also added in arm64 support for drm_clflush_virt_range. v7: Re-order patches, and use correct macro for dcache flush for arm64. v8: Remove ifdef for asm/cacheflush. v9: Rebased v10: Replaced asm/cacheflush with linux/cacheflush v11: Correctly get the sizeof certian addresses. Also rebased to the latest.
