[PATCH] time: Change log level of "NOHZ: local_softirq_pending" message

[Rado Vrbovsky]

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.

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.
