Correct me if I am wrong anywhere. You're wrong. If you execute a code at address A, that does a memory access at address B, and that a page fault occurs, then regs->eip will contain address A, and cr2 will contain address B. Of course, there are cases where regs->eip is the faulting address, but it's not always the case.
