Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 update from Martin Schwidefsky: "Add support to generate code for the latest machine zEC12, MOD and XOR instruction support for the BPF jit compiler, the dasd safe offline feature and the big one: the s390 architecture gets PCI support!! Right before the world ends on the 21st ;-)" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (41 commits) s390/qdio: rename the misleading PCI flag of qdio devices s390/pci: remove obsolete email addresses s390/pci: speed up __iowrite64_copy by using pci store block insn s390/pci: enable NEED_DMA_MAP_STATE s390/pci: no msleep in potential IRQ context s390/pci: fix potential NULL pointer dereference in dma_free_seg_table() s390/pci: use kmem_cache_zalloc instead of kmem_cache_alloc/memset s390/bpf,jit: add support for XOR instruction s390/bpf,jit: add support MOD instruction s390/cio: fix pgid reserved check vga: compile fix, disable vga for s390 s390/pci: add PCI Kconfig options s390/pci: s390 specific PCI sysfs attributes s390/pci: PCI hotplug support via SCLP s390/pci: CHSC PCI support for error and availability events s390/pci: DMA support s390/pci: PCI adapter interrupts for MSI/MSI-X s390/bitops: find leftmost bit instruction support s390/pci: CLP interface s390/pci: base support ...
