In ACPI 6.3 chapter 5.2.27 Heterogeneous Memory Attribute Table (HMAT), The initiator represents processor which access to memory. And in 5.2.27.3 Memory Proximity Domain Attributes Structure, the attached initiator is defined as where the memory controller responsible for a memory proximity domain. With attached initiator information, the topology of heterogeneous memory can be described. Add new machine property 'hmat' to enable all HMAT specific options. Extend CLI of "-numa node" option to indicate the initiator numa node-id. In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report the platform's HMAT tables. Before using initiator option, enable HMAT with -machine hmat=on.
