Hi Muchun,

Thank you for the patch! Yet something to improve:

If you fix the issue, kindly add following tag as appropriate

All errors (new ones prefixed by >>):

cc1: fatal error: cannot open 'kernel/bounds.s' for writing: No such file or directory

It would take a lot of talent for Munchun to have caused this!

Methinks you just ran out of disk space?

Hi Andrew,

Thanks for the reply, I tried to apply this patch to the head of
mainline and I still can reproduce the error in my local machine:
