From bd68f98ba76f43954e9858252a30e6c3b054c146 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Mon, 1 May 2017 13:37:03 -0700 Subject: gpu: nvgpu: Move secure_alloc to struct gk20a Move the function pointer for VPR page allocation to struct gk20a and use it from there. At the same time remove secure_page_alloc pointer and add a direct call to it in probe. Move platform_tegra.h as tegra/linux/platform_gk20a_tegra.h, as it's only declaring functions defined in platform_gk20a_tegra.c to other files in the same directory.
