Re: which is the module for CONFIG_CPU_FREQ_GOV_USERSPACE=m

RobD over at alt.os.linux provided the answer:
"The modules related to CPU_FREQ are:
obj-$(CONFIG_CPU_FREQ) += cpufreq.o
obj-$(CONFIG_CPU_FREQ_GOV_PERFORMANCE) += cpufreq_performance.o
obj-$(CONFIG_CPU_FREQ_GOV_POWERSAVE) += cpufreq_powersave.o
obj-$(CONFIG_CPU_FREQ_GOV_USERSPACE) += cpufreq_userspace.o
obj-$(CONFIG_CPU_FREQ_TABLE) += freq_table.o
obj-$(CONFIG_CPU_FREQ_PROC_INTF) += proc_intf.o
and, scaling_setspeed requires cpufreq_userspace."
