Heiko Carstens 4148575abe s390/uaccess: add cmpxchg_user_key()
Add cmpxchg_user_key() which allows to execute a compare and exchange
on a user space address. This allows also to specify a storage key
which makes sure that key-controlled protection is considered.

This is based on a patch written by Janis Schoetterl-Glausch.
