[PATCH v4 8/8] s390/percpu: Remove one and two byte this_cpu operation implementation

[Heiko Carstens]

There are no one and two byte this_cpu operations within the kernel
(defconfig). However even if there would be, the s390 implementation, which
uses a cmpxchg loop, generates a very large code sequence due to the lack
of native one and two byte cmpxchg instructions.

Remove the s390 implementation and use the generic implementation.
