"Fix the ACPI processor driver initialization ordering after recent
changes to avoid calling init_freq_invariance_cppc() too early on AMD
platforms (Mario Limonciello)"
* tag 'acpi-6.12-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: processor: Move arch_init_invariance_cppc() call later
