  • CPU load dispaly error in SMP mode

Load Average: 100.510% Load: 100.966% Idle: 99.033%

In fact,CPU is doing nothing.

  • priority display unreadable in SMP mode
    in diffrent Schedulers priority is map to a core priority, I think unmap

maybe reasonable when display the infomation

I create a patch about this,see the attachment.
