Merge branches 'acpi-apei', 'acpi-processor', 'acpi-tables', 'acpi-pci' and 'acpi-soc'
* acpi-apei: ACPI / APEI: Release resources if gen_pool_add() fails ACPI / APEI: Get rid of NULL_UUID_LE constant * acpi-processor: ACPI / processor: don't print errors for processorIDs == 0xff * acpi-tables: ACPI: custom_method: fix memory leaks HMAT: Skip publishing target info for nodes with no online memory HMAT: Register attributes for memory hot add HMAT: Register memory-side cache after parsing * acpi-pci: ACPI / PCI: fix acpi_pci_irq_enable() memory leak ACPI/PCI: Remove surplus parentheses from a return statement * acpi-soc: ACPI / LPSS: Save/restore LPSS private registers also on Lynxpoint
