From 4d51985e484dd11d9047dfcd1278ec9ccfb435d5 Mon Sep 17 00:00:00 2001 From: Michael Rodriguez Date: Tue, 22 Mar 2011 16:34:07 -0700 Subject: [PATCH] kernel/cpu.c: fix many errors related to style. Change the printk() calls to have the KERN_INFO/KERN_ERROR stuff, and fixes other coding style errors. Not _all_ of them are gone, though.
