Merge branches 'acpi-tables', 'acpi-numa', 'acpi-sysfs', 'acpi-cppc', 'acpi-thermal' and 'acpi-battery'
Merge ACPI tables parsing code update, NUMA-related ACPI update, CPPC documentation update, ACPI sysfs attributes handling update and ACPI thermal and battery drivers updates for 5.17-rc1: - Add AEST to the list of known ACPI table signatures (Shuuichirou Ishii). - Make ACPI NUMA code take hotpluggable memblocks into account when CONFIG_MEMORY_HOTPLUG is not set (Vitaly Kuznetsov). - Use default_groups in kobj_type in the ACPI sysfs code (Greg Kroah-Hartman). - Rearrange _CPC structure documentation (Andy Shevchenko). - Drop an always true check from the ACPI thermal driver (Adam Borowski). - Add new "not charging" quirk for Lenovo ThinkPads to the ACPI battery driver (Thomas Weißschuh). * acpi-tables: ACPI: tables: Add AEST to the list of known table signatures * acpi-numa: ACPI: NUMA: Process hotpluggable memblocks when !CONFIG_MEMORY_HOTPLUG * acpi-sysfs: ACPI: sysfs: use default_groups in kobj_type * acpi-cppc: ACPI: CPPC: Amend documentation in the comments * acpi-thermal: ACPI: thermal: drop an always true check * acpi-battery: ACPI: battery: Add the ThinkPad "Not Charging" quirk
