Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "The bulk of the s390 patches for 4.13. Some new things but mostly bug fixes and cleanups. Noteworthy changes: - The SCM block driver is converted to blk-mq - Switch s390 to 5 level page tables. The virtual address space for a user space process can now have up to 16EB-4KB. - Introduce a ELF phdr flag for qemu to avoid the global vm.alloc_pgste which forces all processes to large page tables - A couple of PCI improvements to improve error recovery - Included is the merge of the base support for proper machine checks for KVM" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (52 commits) s390/dasd: Fix faulty ENODEV for RO sysfs attribute s390/pci: recognize name clashes with uids s390/pci: provide more debug information s390/pci: fix handling of PEC 306 s390/pci: improve pci hotplug s390/pci: introduce clp_get_state s390/pci: improve error handling during fmb (de)registration s390/pci: improve unreg_ioat error handling s390/pci: improve error handling during interrupt deregistration s390/pci: don't cleanup in arch_setup_msi_irqs KVM: s390: Backup the guest's machine check info s390/nmi: s390: New low level handling for machine check happening in guest s390/fpu: export save_fpu_regs for all configs s390/kvm: avoid global config of vm.alloc_pgste=1 s390: rename struct psw_bits members s390: rename psw_bits enums s390/mm: use correct address space when enabling DAT s390/cio: introduce io_subchannel_type s390/ipl: revert Load Normal semantics for LPAR CCW-type re-IPL s390/dumpstack: remove raw stack dump ...
