Merge tag 's390-6.1-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Alexander Gordeev:
- Fix deadlock in discontiguous saved segments (DCSS) block device
driver. When adding a disk and scanning partitions the scan would not
break out early without a missed flag.
- Avoid using global register variable for current_stack_pointer due to
an old bug in gcc versions prior to gcc-8.4. Due to this bug a broken
code is generated, which leads to stack corruptions.
