    s390: move spectre sysfs attribute code · 4253b0e0
    Martin Schwidefsky authored
    The nospec-branch.c file is compiled without the gcc options to
    generate expoline thunks. The return branch of the sysfs show
    functions cpu_show_spectre_v1 and cpu_show_spectre_v2 is an indirect
    branch as well. These need to be compiled with expolines.
    
    Move the sysfs functions for spectre reporting to a separate file
    and loose an '.' for one of the messages.
