[PATCH 2][Xen-devel] Cpufreq: prevent negative px resident time, add spinlock to avoid race
Cpufreq: prevent negative px resident time, add spinlock to avoid race Due to NOW() value may drift between different cpus, we add protection to prevent negative px resident time. Due to both cpufreq logic and xenpm may race accessing cpufreq_statistic_data, we add spinlock to avoid race.
