Hi Rafael,

Please pull the following cpupower update for Linux 6.12-rc1.

This cpupower update for Linux 6.12-rc1 consists of an enhancement
to cpuidle tool to display the residency value of cpuidle states.
This addition provides a clearer and more detailed view of idle
state information when using cpuidle-info.

diff is attached.

thanks,
-- Shuah
