[Intel-gfx] [PATCH v13 0/5] Use drm_clflush* instead of clflush

[Michael Cheng <michael.cheng@intel.com>]

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.

v13: Drop arm64 implementation for drm_clflush_virt_range. This series will 
focus more on making i915 more architecture neutral by abstracting all clflush
and clflush opt to the drm layer.
