[PATCH] ACPI: Get rid of "registered as cooling_deviceX" messages

[Roland Dreier]

The messages "<xyz> registered as cooling_deviceX" printed by various
ACPI drivers give the same information as just looking at the symlinks
/sys/class/thermal/cooling_deviceX/device.  On a big system, they
clutter up the syslog and take a long time to print on a serial console.

On a 64-thread system I've been lucky enough to play with:

    $ dmesg | grep 'registered as cooling_device' | wc
         64     448    4278

which is getting past tragedy and into the realm of comedy.  We may as
well not print these messages.

Len, still more in my trimming of the boot log on my big box.  If this
makes sense to you, please apply.

Also I think <http://patchwork.kernel.org/patch/50048/> might have
gotten lost somewhere -- you applied the C-state version but not the
equivalent T-state patch.
