Merge tag 'acpi-5.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
"These make an excess warning message go away and fix a recently
introduced boot failure on a vintage machine.

Specifics:

- Change the log level of the "table not found" message in
acpi_table_parse_entries_array() to debug to prevent it from
showing up in the logs unnecessarily (Dan Williams)

- Add a C-state limit quirk for 32-bit ThinkPad T40 to prevent it
from crashing on boot after recent changes in the ACPI processor
driver (Woody Suwalski)"
