Subject: [PATCH 6/6] CPUIDLE: load ACPI properly when CPUIDLE is disabled
Date: Tue, 21 Aug 2007 18:27:07 -0400 [thread overview]
Message-ID: <1187735227.7199.56.camel@callisto.site> (raw)
This patch changes the registration return codes for when CPUIDLE
support is not compiled into the kernel. As a result, the ACPI
processor driver will load properly even if CPUIDLE is unavailable.
However, it may be possible to cleanup the ACPI processor driver further
and eliminate some dead code paths.
Please Apply,
Adam
