Subject: [PATCH v8 11/12] acpi/numa/hmat: Register HMAT at device_initcall level
Date: Wed, 06 Nov 2019 17:43:49 -0800	[thread overview]
Message-ID: <157309102949.1579826.9612009592539745686.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

In preparation for registering device-dax instances for accessing EFI
specific-purpose memory, arrange for the HMAT registration to occur
later in the init process. Critically HMAT initialization needs to occur
after e820__reserve_resources_late() which is the point at which the
iomem resource tree is populated with "Application Reserved"
(IORES_DESC_APPLICATION_RESERVED). e820__reserve_resources_late()
happens at subsys_initcall time.
