Below is a patch from android kernel that maintains a histogram of
suspend times. Please review and provide feedback.
Statistices on the time spent in suspend are kept in
/sys/kernel/debug/sleep_time.

[[email protected]: Re-formatted suspend time table to better fit
expected values. Moved accounting of suspend time into timekeeping core.
Removed CONFIG_SUSPEND_TIME flag and made the feature conditional on
CONFIG_DEBUG_FS. Changed the file name to sleep_time to better fit terminology
in timekeeping core. Changed seq_printf to seq_puts. Tweaked commit message]
