ACPI fixes for 4.18-rc2 - Fix a suspend/resume regression in the ACPI driver for Intel SoCs (LPSS) to make it work on systems where some power management quirks should only be applied for runtime PM and suspend-to-idle and not for suspend-to-RAM (Rafael Wysocki). - Add a system wakeup quirk for Thinkpad X1 Carbon 6th to the ACPI EC driver to avoid drainig battery too fast while suspended to idle on those systems (Mika Westerberg). - Fix an inline stub of acpi_processor_ppc_has_changed() to match the original function definition (Brian Norris).
