Subject: [PATCH] intel_pstate: Turn per cpu printk into pr_debug
Date: Wed, 27 Aug 2014 10:17:08 -0700 [thread overview]
Message-ID: <1409159828-16168-1-git-send-email-andi@firstfloor.org> (raw)
From: Andi Kleen <ak@linux.intel.com>
On larger systems intel_pstate currently spams the boot up
log with its "Intel pstate controlling ..." message for each CPU.
It's the only subsystem that prints a message for each
CPU.
Turn the message into a pr_debug.
