add per_cpu_dyn_array support
allow dyn-array in per_cpu area, allocated dynamically.
usage:
| /* in .h */
| struct kernel_stat {
| struct cpu_usage_stat cpustat;
| unsigned int *irqs;
| };
|
| /* in .c */
| DEFINE_PER_CPU(struct kernel_stat, kstat);
|
| DEFINE_PER_CPU_DYN_ARRAY_ADDR(per_cpu__kstat_irqs, per_cpu__kstat.irqs, sizeof(unsigned int), nr_irqs, sizeof(unsigned long), NULL);
after setup_percpu()/per_cpu_alloc_dyn_array(), the dyn_array in
per_cpu area is ready to use.
