函数名称：Find the best CPU which has the lowest number of managed IRQs allocated

函数原型：static unsigned int matrix_find_best_cpu_managed(struct irq_matrix *m, const struct cpumask *msk)

返回类型：unsigned int

参数：

类型参数名称
struct irq_matrix *m
const struct cpumask *msk
153  allocated等于UINT_MAX
156  best_cpu等于UINT_MAX
159  cm等于per_cpu_ptr(maps, cpu)
161  如果非online或managed_allocated大于allocated则继续下一循环
164  best_cpu等于cpu
165  allocated等于managed_allocated
167  返回:best_cpu
