By requiring 2.6.25 we can get rid of quite a lot of backport work.
2.6.25 was released more than five years ago (April 2011) and wasn't
a long-term kernel either, so there's little point in supporting it
now.

This package provides the latest Linux kernel subsystem enhancements
-for kernels 2.6.24 and above. It is technically possible to support
-kernels < 2.6.24 but more work is required for that.
+for kernels 2.6.25 and above.

- * This module exposes the interface to kernel space for specifying
- * QoS dependencies. It provides infrastructure for registration of:
- *
- * Dependents on a QoS value : register requirements
- * Watchers of QoS value : get notified when target QoS value changes
- *
- * This QoS design is best effort based. Dependents register their QoS needs.
- * Watchers register to keep track of the current QoS needs of the system.
- *
- * There are 3 basic classes of QoS parameter: latency, timeout, throughput
- * each have defined units:
- * latency: usec
- * timeout: usec <-- currently not used.
- * throughput: kbs (kilo byte / sec)
- *
- * There are lists of pm_qos_objects each one wrapping requirements, notifiers
- *
- * User mode requirements on a QOS parameter register themselves to the
- * subsystem by opening the device node /dev/... and writing there request to
- * the node. As long as the process holds a file handle open to the node the
- * client continues to be accounted for. Upon file release the usermode
- * requirement is removed and a new qos target is computed. This way when the
- * requirement that the application has is cleaned up when closes the file
- * pointer or exits the pm_qos_object will get an opportunity to clean up.
