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. * tag 's390-6.1-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: avoid using global register for current_stack_pointer s390/dcssblk: fix deadlock when adding a DCSS
