Nicolas Lacasse 0050e3e71c sysfs: Add (empty) cpu directories for each cpu in /sys/devices/system/cpu.
Numpy needs these.

Also added the "present" directory, since the contents are the same as possible
and online.

Chenggang Qin aeec7a4c00 fs: Support possible and online knobs for cpu
Some linux commands depend on /sys/devices/system/cpu/possible, such
as 'lscpu'.

Add 2 knobs for cpu:
/sys/devices/system/cpu/possible
/sys/devices/system/cpu/online
Both the values are '0 - Kernel.ApplicationCores()-1'.
