Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "This patch set contains the main portion of the changes for 3.18 in regard to the s390 architecture. It is a bit bigger than usual, mainly because of a new driver and the vector extension patches. The interesting bits are: - Quite a bit of work on the tracing front. Uprobes is enabled and the ftrace code is reworked to get some of the lost performance back if CONFIG_FTRACE is enabled. - To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the IPTE range facility is added. - The rwlock code is re-factored to improve writer fairness and to be able to use the interlocked-access instructions. - The kernel part for the support of the vector extension is added. - The device driver to access the CD/DVD on the HMC is added, this will hopefully come in handy to improve the installation process. - Add support for control-unit initiated reconfiguration. - The crypto device driver is enhanced to enable the additional AP domains and to allow the new crypto hardware to be used. - Bug fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (39 commits) s390/ftrace: simplify enabling/disabling of ftrace_graph_caller s390/ftrace: remove 31 bit ftrace support s390/kdump: add support for vector extension s390/disassembler: add vector instructions s390: add support for vector extension s390/zcrypt: Toleration of new crypto hardware s390/idle: consolidate idle functions and definitions s390/nohz: use a per-cpu flag for arch_needs_cpu s390/vtime: do not reset idle data on CPU hotplug s390/dasd: add support for control unit initiated reconfiguration s390/dasd: fix infinite loop during format s390/mm: make use of ipte range facility s390/setup: correct 4-level kernel page table detection s390/topology: call set_sched_topology early s390/uprobes: architecture backend for uprobes s390/uprobes: common library for kprobes and uprobes s390/rwlock: use the interlocked-access facility 1 instructions s390/rwlock: improve writer fairness s390/rwlock: remove interrupt-enabling rwlock variant. s390/mm: remove change bit override support ...
