[Qemu-devel] [PATCH v4 2/8] hw/acpi: Do not create memory hotplug method when handler is not defined |

From: Samuel Ortiz <address@hidden>
With Hardware-reduced ACPI, the GED device will manage ACPI
hotplug entirely. As a consequence, make the memory specific
events AML generation optional. The code will only be added
when the method name is not NULL.
