Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "There are two memory management related changes, the CMMA support for KVM to avoid swap-in of freed pages and the split page table lock for the PMD level. These two come with common code changes in mm/. A fix for the long standing theoretical TLB flush problem, this one comes with a common code change in kernel/sched/. Another set of changes is Heikos uaccess work, included is the initial set of patches with more to come. And fixes and cleanups as usual" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (36 commits) s390/con3270: optionally disable auto update s390/mm: remove unecessary parameter from pgste_ipte_notify s390/mm: remove unnecessary parameter from gmap_do_ipte_notify s390/mm: fixing comment so that parameter name match s390/smp: limit number of cpus in possible cpu mask hypfs: Add clarification for "weight_min" attribute s390: update defconfigs s390/ptrace: add support for PTRACE_SINGLEBLOCK s390/perf: make print_debug_cf() static s390/topology: Remove call to update_cpu_masks() s390/compat: remove compat exec domain s390: select CONFIG_TTY for use of tty in unconditional keyboard driver s390/appldata_os: fix cpu array size calculation s390/checksum: remove memset() within csum_partial_copy_from_user() s390/uaccess: remove copy_from_user_real() s390/sclp_early: Return correct HSA block count also for zero s390: add some drivers/subsystems to the MAINTAINERS file s390: improve debug feature usage s390/airq: add support for irq ranges s390/mm: enable split page table lock for PMD level ...
