From 73540690f71280a2bdda51b45203fd4ed43a1760 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Wed, 16 Nov 2011 22:42:44 -0800 Subject: [PATCH] intel: Define intel_miptree_check_level_layer() This is a small helper function that asserts that a given level and layer are valid for a miptree. I will be extensively using it in the future miptree HiZ functions.
