Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "The main new feature is machine support for System zEC12 including transactional memory, runtime instrumentation, support for scm block devices via eadm subchannels, and support for CEX4 crypto cards. In addition there are some nice improvements: bpf jit compiler, arch backend for cmpxchg_double, relative exception table entries, dasd partition detection independent from the dasd driver ioctls, and cpu cache information in /proc/cpuinfo and /sys/device/cpu. And last but not least a series of cleanup patches from Heiko." Fix up trivial add-add conflict in arch/s390/Kconfig due to commit b952741c8079 ("cputime: Generalize CONFIG_VIRT_CPU_ACCOUNTING") * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (76 commits) s390: update defconfig s390/jump label,nss: let shared kernel support depend on !JUMP_LABEL s390/disassembler: fix decoding of risblg instruction s390/bpf,jit: add support for BPF_S_ANC_ALU_XOR_X instruction s390/traps: move call to print_modules() out of show_regs() s390/mm: mark free_initrd_mem() as __init s390/dasd: check count address during online setting drivers/s390/char/monreader.c: fix error return code s390/cmpxchg,percpu: implement cmpxchg_double() s390/percpu: implement this_cpu_add_return() s390/percpu: implement this_cpu_xchg() s390/kexec: remove CONFIG_KEXEC s390/irq: use designated initializers for irq class array s390: add uninitialized_var() to suppress false positive compiler warnings s390/crashdump: move fill_cpu_elf_notes() prototype to header file s390/process: add missing header include s390/ptrace: add missing ifdef s390/ipl,decrompressor: disable branch profiling s390/perf_events: compile only for CONFIG_64BIT s390/tape: remove even more tape block leftovers ...
