ACPI, cpuidle: Clarify C-state description in sysfs

[net-next-2.6.git] / Documentation / 00-INDEX

This is a brief list of all the files in ./linux/Documentation and what
they contain. If you add a documentation file, please list it here in
alphabetical order as well, or risk being hunted down like a rabid dog.
Please try and keep the descriptions small enough to fit on one line.
