Can anyone help me to understand the usage of 'microcode' in /sys/devices/system/cpu/cpu0/.

-------------------------------------------------------------------------------------

mysystem: /sys/devices/system/cpu/cpu0/ #ls

processor_flags reload version

-------------------------------------------------------------------------------------

What are the usages of 'processor_flags', 'reload' and 'version'?

I have searched in the Documentation and LKML,but failed to find helpful information.

Can Anyone who know those give me some more information about this?

Any help will be appreciated!
