From 3e490042a80f82df80141fce1dbef1baa7850160 Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Tue, 28 Feb 2017 17:28:07 +0200 Subject: drm/i915/gtt: Make I915_PDPES_PER_PDP inline function The macro takes a vm pointer at some sites, and dev_priv on others We were saved as the internal macro never deferences the pointer given. As the number of pdpes depend on vm configuration, make it as a inline function that accepts vm pointer.
