From d0380e6c3c0f6edb986d8798a23acfaf33d5df23 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 29 Apr 2013 16:17:18 -0700 Subject: early_printk: consolidate random copies of identical code The early console implementations are the same all over the place. Move the print function to kernel/printk and get rid of the copies.
