From b1de0d139c97a6078bbada6cf2d27c30ce127a97 Mon Sep 17 00:00:00 2001 From: Mitchel Humpherys Date: Fri, 6 Jun 2014 14:38:30 -0700 Subject: mm: convert some level-less printks to pr_* printk is meant to be used with an associated log level. There are some instances of printk scattered around the mm code where the log level is missing. Add a log level and adhere to suggestions by scripts/checkpatch.pl by moving to the pr_* macros. Also add the typical pr_fmt definition so that print statements can be easily traced back to the modules where they occur, correlated one with another, etc. This will require the removal of some (now redundant) prefixes on a few print statements.
