Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull first batch of s390 updates from Martin Schwidefsky: "The most interesting change is that Martin converted s390 to generic hardirqs. Which means that all current architectures have been converted and that CONFIG_GENERIC_HARDIRQS can be removed. Martin prepared a patch for that already (see genirq branch), but the best time to merge that is probably at the end of the merge window / begin of -rc1. Another patch converts s390 to software referenced bits instead of relying on the reference bit in the storage key. Therefore s390 doesn't use storage keys anymore, except for kvm. Besides that we have improvements, cleanups and fixes in PCI, DASD and all over the place." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (32 commits) s390/pci: use virtual memory for iommu bitmap s390/cio: fix unlocked access of global bitmap s390/pci: update function handle after resume from hibernate s390/pci: try harder to modify a function s390/pci: split lpf s390/hibernate: add early resume function s390/pci: add recover sysfs knob s390/pci: use claim_resource s390/pci/hotplug: convert to be builtin only s390/mm: implement software referenced bits s390/dasd: fix statistics for recovered requests s390/tx: allow program interruption filtering in user space s390/pgtable: fix mprotect for single-threaded KVM guests s390/time: return with irqs disabled from psw_idle s390/kprobes: add support for compare and branch instructions s390/switch_to: fix save_access_regs() / restore_access_regs() s390/bitops: fix inline assembly constraints s390/dasd: enable raw_track_access reads without direct I/O s390/mm: introduce ptep_flush_lazy helper s390/time: clock comparator revalidation ...
