From f58e1f53de52a70391b6478617311207c7203363 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 8 Dec 2009 22:30:50 -0800 Subject: [PATCH] arch/x86/kernel/microcode*: Use pr_fmt() and remove duplicated KERN_ERR prefix - Use #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt - Remove "microcode: " prefix from each pr_ - Fix duplicated KERN_ERR prefix - Coalesce pr_ format strings - Add a space after an exclamation point No other change in output.
