Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "The new features and main improvements in this merge for v4.9 - Support for the UBSAN sanitizer - Set HAVE_EFFICIENT_UNALIGNED_ACCESS, it improves the code in some places - Improvements for the in-kernel fpu code, in particular the overhead for multiple consecutive in kernel fpu users is recuded - Add a SIMD implementation for the RAID6 gen and xor operations - Add RAID6 recovery based on the XC instruction - The PCI DMA flush logic has been improved to increase the speed of the map / unmap operations - The time synchronization code has seen some updates And bug fixes all over the place" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (48 commits) s390/con3270: fix insufficient space padding s390/con3270: fix use of uninitialised data MAINTAINERS: update DASD maintainer s390/cio: fix accidental interrupt enabling during resume s390/dasd: add missing \n to end of dev_err messages s390/config: Enable config options for Docker s390/dasd: make query host access interruptible s390/dasd: fix panic during offline processing s390/dasd: fix hanging offline processing s390/pci_dma: improve lazy flush for unmap s390/pci_dma: split dma_update_trans s390/pci_dma: improve map_sg s390/pci_dma: simplify dma address calculation s390/pci_dma: remove dma address range check iommu/s390: simplify registration of I/O address translation parameters s390: migrate exception table users off module.h and onto extable.h s390: export header for CLP ioctl s390/vmur: fix irq pointer dereference in int handler s390/dasd: add missing KOBJ_CHANGE event for unformatted devices s390: enable UBSAN ...
