* master.kernel.org:/pub/scm/linux/kernel/git/davej/cpufreq:
[CPUFREQ] Don't take semaphore in cpufreq_quick_get()
[CPUFREQ] Support different families in fid/did to frequency conversion
[CPUFREQ] cpufreq_stats: misc cpuinit section annotations
[CPUFREQ] implement !CONFIG_CPU_FREQ stub for cpufreq_unregister_notifier()
[CPUFREQ] mark hotplug notifier callback as __cpuinit
[CPUFREQ] Only check for transition latency on problematic governors (kconfig fix)
[CPUFREQ] allow ondemand and conservative cpufreq governors to be used as default
[CPUFREQ] move policy's governor initialisation out of low-level drivers into cpufreq core
[CPUFREQ] Longhaul - Add support for PM133 northbridge
[CPUFREQ] x86: use num_online_nodes to get physical cpus numbers for
