This ioctl is in the drm-intel-next tree as b635991. v2: Update based on Mika's kernel work. v3: Fix compile failures from last-minute typos. Sigh. v4: Import the actual changes from the kernel i915_drm.h. Only comments on some fields of drm_i915_reset_stats differed. There are still some deltas between the kernel i915_drm.h and the one in libdrm, but those can be resolved in other patches.
