MTK6577修改成四核同理修改成其他个数的核。修改 kernel/drivers/base/cpu.c 文件
1. show_cpus_attr 函数改为
static ssize_t show_cpus_attr(struct sysdev_class *class,
   struct sysdev_class_attribute *attr,
   char *buf)
{
   struct cpu_attr *ca = container_of(attr, struct cpu_attr, attr);
   int n = cpulist_scnprintf(buf, PAGE_SIZE-2, *(ca->map));

if( n >= 2 )
   {
   buf[2] = '3';
   }
   buf[n++] = '\n';
   buf[n] = '\0';
   return n;
}

2. 添加函数
static ssize_t print_cpus_cpu2(struct device *dev,
   struct device_attribute *attr, char *buf)
{
   int n = snprintf(buf, PAGE_SIZE-2, "%d\n", 11);
   return n;
}
static DEVICE_ATTR(cpu2, 0444, print_cpus_cpu2, NULL);

static ssize_t print_cpus_cpu3(struct device *dev,
   struct device_attribute *attr, char *buf)
{
   int n = snprintf(buf, PAGE_SIZE-2, "%d\n", 11);
   return n;
}
static DEVICE_ATTR(cpu3, 0444, print_cpus_cpu3, NULL);

3.cpu_sysdev_class_attrs 数组改成
static struct sysdev_class_attribute *cpu_sysdev_class_attrs[] = {
#ifdef CONFIG_ARCH_CPU_PROBE_RELEASE
   &attr_probe,
   &attr_release,
#endif
   &cpu_attrs[0].attr,
   &cpu_attrs[1].attr,
   &cpu_attrs[2].attr,
&dev_attr_cpu2.attr,
   &dev_attr_cpu3.attr,
   &attr_kernel_max,
   &attr_offline,
   NULL
};

以上可以欺骗360优化大师安兔兔让其显示为四核
