Introduce a new ioctl API and in-kernel API to verify if a random protected key is still valid. A protected key is invalid when its wrapping key verification pattern does not match the verification pattern of the LPAR. Each time an LPAR is activated, a new LPAR wrapping key is generated and the wrapping key verification pattern is updated. Both APIs are described in detail in the header files arch/s390/include/asm/pkey.h and arch/s390/include/uapi/asm/pkey.h.
