Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.1-rc3

with top-most commit 31d4c528cea4023cf36f6148c03bb960cedefeef

cpufreq: scpi: Fix use after free

on top of commit 8c2ffd9174779014c3fe1f96d9dc3641d9175f00

Linux 5.1-rc2

to receive power management fixes for 5.1-rc3.

These fix CPU base frequency reporting in the intel_pstate
driver and a use-after-free in the scpi-cpufreq driver.

Specifics:

- Fix the ACPI CPPC library to actually follow the specification
when decoding the guaranteed performance register information and
make the intel_pstate driver fall back to the nominal frequency
when reporting the base frequency if the guaranteed performance
register information is not there (Srinivas Pandruvada).

- Fix use-after-free in the exit callback of scpi-cpufreq left after
an update during the 5.0 development cycle (Vincent StehlÃ).

Thanks!
