Subject: [PATCH 3/3] cpuidle: Don't enable all governors by default
Date: Mon, 11 Jan 2016 17:43:02 +0100	[thread overview]
Message-ID: <20160111174302.34294818@endymion.delvare> (raw)
In-Reply-To: <20160111173915.63ec1bcd@endymion.delvare>

Since commit d6f346f2d2 ("cpuidle: improve governor Kconfig options")
the best cpuidle governor is selected automatically. There is little
point in additionally selecting the other as it will not be used. So
don't make it the default.

Being able to select more than one governor is still good for
developers booting with cpuidle_sysfs_switch.

This fixes the second half of bug #65531:
