Subject: [PATCH 1/2] acpi-cpufreq: Fix CPU_ANY CPUFREQ_{PRE,POST}CHANGE notification
Date: Tue, 27 Apr 2010 16:57:41 +0200	[thread overview]
Message-ID: <1272380262-23671-2-git-send-email-trenn@suse.de> (raw)
In-Reply-To: <1272380262-23671-1-git-send-email-trenn@suse.de>

This has been found be review.
Currently PRE/POSTCHANGE events seem to only be thrown for one core
if the BIOS tells us to run in CPU_ANY mode (switching one/any
of the depending cores is enough).
