Hi Linus,

pm-6.1-rc7
with top-most commit 1056d314709d0607a22e589c54b1e47e0da57b9d
Documentation: add amd-pstate kernel command line options
on top of commit eb7081409f94a9a8608593d0fb63a1aa3d6f95d8
Linux 6.1-rc6
to receive power management fixes for 6.1-rc7.
These revert a recent change in the schedutil cpufreq governor that
had not been expected to make any functional difference, but turned
out to introduce a performance regression, fix an initialization issue
in the amd-pstate driver and make it actually replace the venerable
ACPI cpufreq driver on the supported systems by default.
Specifics:
- Revert a recent schedutil cpufreq governor change that introduced
a performance regression on Pixel 6 (Sam Wu).
- Fix amd-pstate driver initialization after running the kernel via
kexec (Wyes Karny).
- Turn amd-pstate into a built-in driver which allows it to take
precedence over acpi-cpufreq by default on supported systems and
amend it with a mechanism to disable this behavior (Perry Yuan).
- Update amd-pstate documentation in accordance with the other changes
made to it (Perry Yuan).
Thanks!
