Liav A 75f01692b4 Kernel+Userland: Move /sys/firmware/power_state to /sys/kernel directory 
Let's put the power_state global node into the /sys/kernel directory,
because that directory represents all global nodes and variables being
related to the Kernel. It's also a mutable node, that is more acceptable
being in the mentioned directory due to the fact that all other files in
the /sys/firmware directory are just firmware blobs and are not mutable
at all.

Name

shutdown - Power off the machine

$ shutdown

Description

shutdown instructs the kernel to power off the machine immediately.

Notes

The shutdown utility opens the /sys/kernel/power_state node and writes the magic value "2" to instruct the kernel to power off the machine.
