Merge tag 'turbostat-2025.09.09' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux 

Pull turbostat updates from Len Brown:
 "tools/power turbostat: version 2025.09.09

   - Probe and display L3 Cache topology

   - Add ability to average an added counter (useful for pre-integrated
     "counters", such as Watts)

   - Break the limit of 64 built-in counters

   - Assorted bug fixes and minor feature tweaks"
