Merge tag 's390-6.17-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Alexander Gordeev:
- ptep_modify_prot_start() may be called in a loop, which might lead to
the preempt_count overflow due to the unnecessary preemption
disabling. Do not disable preemption to prevent the overflow
- Events of type PERF_TYPE_HARDWARE are not tested for sampling and
return -EOPNOTSUPP eventually.
Instead, deny all sampling events by CPUMF counter facility and
return -ENOENT to allow other PMUs to be tried
- The PAI PMU driver returns -EINVAL if an event out of its range. That
aborts a search for an alternative PMU driver.
Instead, return -ENOENT to allow other PMUs to be tried
