+From 04c0746663bd3ae3cce5e02d5b32c8ade2a833b8 Mon Sep 17 00:00:00 2001
+From: Thierry Reding <treding@nvidia.com>

+Subject: [PATCH] drm/tegra: gem: Make __tegra_gem_mmap() available more widely
+
+This function allows mapping a GEM object into a virtual memory address
+space, which makes it useful outside of the GEM code.
+
+While at it, rename the function so it doesn't clash with the function
+that implements the DRM_TEGRA_GEM_MMAP IOCTL.
