From af0265dfeffa42256a4d52b73509f91c7e9ed113 Mon Sep 17 00:00:00 2001 From: Matthew Auld Date: Mon, 6 Dec 2021 11:25:38 +0000 Subject: [PATCH] drm/i915/migrate: fix length calculation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit 31d70749bfe110593fbe8bf45e7c7788c7d85035 ] No need to insert PTEs for the PTE window itself, also foreach expects a length not an end offset, which could be gigantic here with a second engine.
