Hi, everybody:
     What information should be written to
/sys/devices/system/cpu/probe to add a cpu In X86?
     And, what information should be written to
/sys/devices/system/cpu/release to remove a  cpu In X86?
      I have read the
/Documentation/ABI/testing/sysfs-devices-system-cpu. It says that
      probe:writes to this file will dynamically add a CPU to the
system. Information written to the file to add CPU's is architeture
specific.
      release: writes to this file will dynamically remove a CPU to
the system. Information written to the file to remove CPU's is
architeture specific.
      I just want to know what information should be written to those file.
      Any help will be appreciated!
