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
