Ah, it is probably exercising the -EFAULT path, and the code in Andrew's tree goes into an infinite loop I think.
We can't test for a fault off the atomic copy, because that needn't indicate an unmapped area. What we need to do is change fault_in_pages_readable to return ret, and catch and return that in the caller if it is an error.
My usual workstation is down ATM otherwise I would send you a patch. Unless someone beats me to it, I'll send you one tomorrow.
Thanks, Nick
