From c767a54ba0657e52e6edaa97cbe0b0a8bf1c1655 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 21 May 2012 19:50:07 -0700 Subject: x86/debug: Add KERN_ to bare printks, convert printks to pr_ Use a more current logging style: - Bare printks should have a KERN_ for consistency's sake - Add pr_fmt where appropriate - Neaten some macro definitions - Convert some Ok output to OK - Use "%s: ", __func__ in pr_fmt for summit - Convert some printks to pr_ Message output is not identical in all cases.
