Christoph Hellwig eab0c6089b maccess: unify the probe kernel arch hooks 
Currently architectures have to override every routine that probes
kernel memory, which includes a pure read and strcpy, both in strict
and not strict variants.  Just provide a single arch hooks instead to
make sure all architectures cover all the cases.
