It seems that bitmaps are redundant and we can remove them without causing much
trouble.
Let's try to do that!
There should be no functional changes, but it may be helpful if anyone can point
out tests/benchmarks that could show any difference in performance.

Michał Winiarski (8):
  drm/i915/gtt: Don't pass ppgtt to ppgtt_cleanup_4lvl
  drm/i915/gtt: Rename orig_start/orig_length
  drm/i915/gtt: Extract unwind to separate function for
    gen6_alloc_va_range
  drm/i915/gtt: Don't use temp bitmaps to unwind gen8_alloc_va_range
  drm/i915/gtt: Purge temp bitmaps
  drm/i915: Prepare i915_page_table_entry_map tracepoint for bitmap
    purge
  drm/i915/gtt: Purge page tracking bitmaps
  drm/i915: Clear range when unbinding closed vma
