From bdf765071a8b573f7b1ba14c02881fa3e623825e Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Fri, 30 Jan 2015 13:57:01 -0500 Subject: [PATCH] drm/tegra: gem: Return 64-bit offset for mmap(2) On 64-bit targets, tegra_gem_mmap() only returns a partial offset to userspace. As such, subsequent calls to mmap(2) may fail. Change the arguments to use a 64-bit offset to fix this.
