It's a patch from Andrew Morton. But it seems that the patches commit id
from Andrew's tree are not constant. Anyway I just fetched the latest
linux-next tree and found this issue was already fixed by commit 3a5f4236fec1
("uaccess-reimplement-probe_kernel_address-using-probe_kernel_read-fix-fix").

Thanks,
