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. Link: https://lore.kernel.org/r/20230224100237.3247871-3-hca@linux.ibm.comSigned-off-by: Heiko Carstens <hca@linux.ibm.com>
