    perf tools: Allow building for ARM · 58e9f941
    Jamie Iles authored
    Add definitions of rmb() and cpu_relax() and include the ARM
    unistd.h header. The __kuser_memory_barrier helper in the helper
    page is used to provide the correct memory barrier depending on
    the CPU type.
    
    [ The rmb() will work on v6 and v7, segfault on v5. Dynamic
      detection to add v5 support will be added later. ]
