Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Martin Schwidefsky: "The big thing in this second merge for s390 is the new eBPF JIT from Michael which replaces the old 32-bit backend. The remaining commits are bug fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/pci: add locking for fmb access s390/pci: extract software counters from fmb s390/dasd: Fix unresumed device after suspend/resume having no paths s390/dasd: fix unresumed device after suspend/resume s390/dasd: fix inability to set a DASD device offline s390/mm: Fix memory hotplug for unaligned standby memory s390/bpf: Add s390x eBPF JIT compiler backend s390: Use bool function return values of true/false not 1/0
