Heiko Carstens 5e02c74905 s390/cpum_sf: use READ_ONCE_ALIGNED_128() instead of 128-bit cmpxchg 
Use READ_ONCE_ALIGNED_128() to read the previous value in front of a
128-bit cmpxchg loop, instead of (mis-)using a 128-bit cmpxchg operation to
do the same.

This makes the code more readable and is faster.
