Christian Borntraeger 6af7eea2ae [S390] s390: disable change bit override ... commit 6a985c6194 ([S390] s390: use change recording override for kernel mapping) deactivated the change bit recording for the kernel mapping to improve the performance. This works most of the time, but there are cases (e.g. kernel runs in home space, futex atomic compare xcmg) where we modify user memory with the kernel mapping instead of the user mapping. Instead of fixing these cases, this patch just deactivates change bit override to avoid future problems with other kernel code that might use the kernel mapping for user memory.
