From 97066c93d6552e25e9bbe4dd501d348820d68c19 Mon Sep 17 00:00:00 2001
From: Felix Kuehling <Felix.Kuehling@amd.com>
Date: Thu, 3 Mar 2016 19:13:20 -0500
Subject: [PATCH 0377/1110] drm/amdgpu: Fix two bugs in
amdgpu_vm_bo_split_mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Off-by-one: last is inclusive, so the maximum is start + max_size - 1
Wrong unit: addr is in bytes, max_size is in pages
