If anyone has any objections, please let me know. ------------------ From: Thomas Zimmermann commit 760bbc58c2c833dec0ee38dd959f4f2f4084fc57 upstream. The screen_buffer field in struct fb_info contains the kernel address of the first byte of framebuffer memory. Do not add the display offset. This offset only describes scrolling during scanout.
