Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 changes from Martin Schwidefsky: "No new functions, a few changes to make the code more robust, some cleanups and bug fixes." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (21 commits) s390/vtimer: rework virtual timer interface s390/dis: Add the servc instruction to the disassembler. s390/comments: unify copyright messages and remove file names s390/lgr: Add init check to lgr_info_log() s390/cpu init: use __get_cpu_var instead of per_cpu s390/idle: reduce size of s390_idle_data structure s390/idle: fix sequence handling vs cpu hotplug s390/ap: resend enable adapter interrupt request. s390/hypfs: Add missing get_next_ino() s390/dasd: add shutdown action s390/ipl: Fix ipib handling for "dumpreipl" shutdown action s390/smp: make absolute lowcore / cpu restart parameter accesses more robust s390/vmlogrdr: cleanup driver attribute usage s390/vmlogrdr: cleanup device attribute usage s390/ccwgroup: remove unused ccwgroup_device member s390/cio/chp: cleanup attribute usage s390/sigp: use sigp order code defines in assembly code s390/smp: use sigp cpu status definitions s390/smp/kvm: unifiy sigp definitions s390/smp: remove redundant check ...
