Saravana Kannan (5): cpufreq: Don't wait for CPU to going offline to restart governor cpufreq: Keep track of which CPU owns the kobj/sysfs nodes separately cpufreq: Don't destroy/realloc policy/sysfs on hotplug/suspend cpufreq: Properly handle physical CPU hot-add/hot-remove cpufreq: Delete dead code related to policy save/restore drivers/cpufreq/cpufreq.c | 238 ++++++++++++++++++---------------------------- include/linux/cpufreq.h | 1 + 2 files changed, 93 insertions(+), 146 deletions(-) -- 1.8.2.1 The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
