From 2a2c16af5f9f1ccfc93a13e820d5381e5c881e92 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Wed, 18 Apr 2018 12:59:00 -0700 Subject: gpu: nvgpu: Move Linux files away from common Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.
