Linus Torvalds e59a039119 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
