    Pull arch/csky updates from Guo Ren:
     "Here are three main features (cpu_hotplug, basic ftrace, basic perf)
      and some bugfixes:
    
      Features:
       - Add CPU-hotplug support for SMP
       - Add ftrace with function trace and function graph trace
       - Add Perf support
       - Add EM_CSKY_OLD 39
       - optimize kernel panic print.
       - remove syscall_exit_work
    
      Bugfixes:
       - fix abiv2 mmap(... O_SYNC) failure
       - fix gdb coredump error
       - remove vdsp implement for kernel
       - fix qemu failure to bootup sometimes
       - fix ftrace call-graph panic
       - fix device tree node reference leak
       - remove meaningless header-y
       - fix save hi,lo,dspcr regs in switch_stack
       - remove unused members in processor.h"
