From af98714e5d05fcbf7638ea4b53d158d96d693bf2 Mon Sep 17 00:00:00 2001 From: Michel Thierry Date: Wed, 29 Jul 2015 17:23:59 +0100 Subject: [PATCH] drm/i915: batch_obj vm offset must be u64 Otherwise it can overflow in 48-bit mode, and cause an incorrect exec_start. Before commit 5f19e2bffa63a91cd4ac1adcec648e14a44277ce ("drm/i915: Merged the many do_execbuf() parameters into a structure"), it was already an u64.
