x86: cpu architecture debug code
Introduce: cat /sys/kernel/debug/x86/cpu/* for Intel and AMD processors to view / debug the state of each CPU. By using this we can debug whole range of registers and other cpu information for debugging purpose and monitor how things are changing. This can be useful for developers as well as for users.
