ANBZ: #20511 The "scan" command of the cmn700 cache scan misc device file can take up to several hundreds milliseconds. The CPU utilization during command run will be 100%. Although use cond_sched() during "scan" running to release CPU resource for other workloads, the high CPU utilization may be undesirable. So, in the patch, add "cpu_percent" parameter to "set_param" command of the misc device file. If "cpu_percent" is less than 100, use schedule_timeout_interruptible() in "scan" command running to reduce the CPU usage to the specified value.
