Add copy_from/to_user_key functions, which perform storage key checking. These functions can be used by KVM for emulating instructions that need to be key checked. These functions differ from their non _key counterparts in include/linux/uaccess.h only in the additional key argument and must be kept in sync with those. Since the existing uaccess implementation on s390 makes use of move instructions that support having an additional access key supplied, we can implement raw_copy_from/to_user_key by enhancing the existing implementation.
