Subject: probe_kernel_address() causes MCA on bogus address

This is a noticed side effect of trying to redo the function pointer
handling.  This code:

        void *p1 = 0xdeadbeefdead0000, *p2 = 0xfeeddeadfeedbeef;

        probe_kernel_address(p1, p2);

causes an immediate MCA and reboot on my HP zx2000 wherever I execute it
in the kernel.  It's supposed to return -EFAULT.
