Merge tag 'linux-cpupower-6.12-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shuah/linux
Merge a cpupower utility update for 6.12 from Shuah Khan: "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." * tag 'linux-cpupower-6.12-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shuah/linux: tools/cpupower: display residency value in idle-info
