Subject: [PATCH] tick: Change log level of NOHZ: local_softirq_pending message
The "NOHZ: local_softirq_pending" message is a largely informational
message. This makes extra work for customers that have a policy of
investigating all kernel log messages logged at <= KERN_ERR log level.
This patch sets the message to a different log level.
[ tglx: Use pr_warn() ]
