Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Martin Schwidefsky: "A couple of system call updates. The two new system calls userfaultfd and membarrier have been added, as well as the 17 direct calls for the multiplexed socket system calls. In addition the system call compat wrappers have been flagged as notrace functions and a few wrappers could be removed. And bug fixes for the vector register handling, cpu_mf, suspend/resume, compat signals, SMT cputime accounting and the zfcp dumper" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: wire up separate socketcalls system calls s390/compat: remove superfluous compat wrappers s390/compat: do not trace compat wrapper functions s390/s390x: allocate sys_membarrier system call number s390/configs//zfcpdump_defconfig: Remove CONFIG_MEMSTICK s390: wire up userfaultfd system call s390/vtime: correct scaled cputime for SMT s390/cpum_cf: Corrected return code for unauthorized counter sets s390/compat: correct uc_sigmask of the compat signal frame s390: fix floating point register corruption s390/hibernate: fix save and restore of vector registers
