* Fix things I misadvised to Nate Lawson:yar2006-08-071-28/+44
| | | | | | | | | | | | | | - "Ns No" is redundant, so reduce it to just "Ns"; - use Li to mark up CPU and system power states because here they are just strings to be typed literally (add more such mark-up as well); - the best practice of typesetting tells us to use an en-dash to indicate a closed range; fortunately, groff_char(7) provides such a symbol. In addition, consistently use a comma between independent clauses coordinated by a conjunction. Pointed out by: ru (mark-up part) MFC after: 3 days

* Rework acpi_cpu_idle() to select the next idle state before sleeping, notnjl2004-06-051-5/+4
| | | | | | | | | | | | | | after. Unify the paths for all Cx states. Remove cpu_idle_busy and instead do the little profiling we need before re-enabling interrupts. Use 1 quantum as estimate for C1 sleep duration since the timer interrupt is the main reason we wake. While here, change the cx_history sysctl to cx_usage and report statistics for which idle states were used in terms of percent. This seems more intuitive than counters. Remove the cx_stats structure since it's no longer used. Update the man page. Change various types which do not need explicit size.
