33 * Backport work for QoS dependencies (kernel/pm_qos_params.c)

36 * ipw2100 now makes use of:
38 * pm_qos_add_requirement(),
39 * pm_qos_update_requirement() and
40 * pm_qos_remove_requirement() from it
42 * mac80211 uses the network latency to determine if to enable or not
43 * dynamic PS. mac80211 also and registers a notifier for when
44 * the latency changes. Since older kernels do no thave pm-qos stuff
45 * we just implement it completley here and register it upon cfg80211
46 * init. I haven't tested ipw2100 on 2.6.24 though.
48 * This pm-qos implementation is copied verbatim from the kernel
49 * written by mark gross mgross@linux.intel.com. You don't have
50 * to do anythinig to use pm-qos except use the same exported
51 * routines as used in newer kernels. The compat_pm_qos_power_init()
52 * defned below is used by the compat module to initialize pm-qos.
