     - rework of the vdso code to avoid the use of the access register mode
    
     - use perf AUX buffers for the transport of diagnostic sample data
    
     - add perf_regs and user stack dump support
    
     - enable perf call graphs for user space programs
    
     - add perf register support for floating-point registers
