I've attached a patch that adds KEY_HIBERNATE and clarifies the uses of
KEY_SUSPEND and KEY_SLEEP.
Please consider. Thanks.

Subject: [PATCH] INPUT: add KEY_HIBERNATE and clarify the uses of KEY_SUSPEND and KEY_SLEEP
Add a new key define that is used for sleeping to disk.
In userspace we've agreed with the following nomenclature:
- standby = sleep CPU and devices (not really used any more)
- suspend = sleep to memory (quite fast)
- hibernate = sleep to disk (slow)
We've already converted Xorg, HAL, and most of userspace to use the same names.
Adding a new key should reduce the confusion where:
KEY_SUSPEND was mapped to XF86Standby, XF86Hibernate or XF86Sleep
KEY_SLEEP was mapped to XF86Hibernate or XF86Standby
With this patch, the sleep keys can be labeled consistently all the way
through the stack. Other patches to device drivers are to follow.
