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.
v12: Drop include of cacheflush.h and use caches_clean_inval_pou instead of dcache_clean_inval_poc, since it is not exported for other modules to use.
