drm/i915: Remove _entry from PPGTT page structures
Lets try to keep this consistent: Page Directory Pointer (PDP). Page Directory (PD), also known as page directory pointer entries. Page Table (PT), also known as page directory entries. s/struct i915_page_table_entry/struct i915_page_table/ s/struct i915_page_directory_entry/struct i915_page_directory/ s/struct i915_page_directory_pointer_entry/struct i915_page_directory_pointer/ Suggested-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Signed-off-by: Michel Thierry <michel.thierry@intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
