SVN rev 209213 on 2010-06-15 19:14:39Z by jhb
When updating individual CPU's lowest Cx state to use, never set it to a
state lower than the lowest one supported by the current CPU. This closes
some races with changes to the hw.acpi.cpu_cx_lowest sysctl while Cx
states for individual CPUs were changing (e.g. unplugging the AC adapter
of a laptop) that could result in panics.
