If anyone has any objections, please let me know. ------------------ From: Shuai Xue [ Upstream commit 7c3643f204edf1c5edb12b36b34838683ee5f8dc ] The Generic Initiator Affinity Structure in SRAT table uses device handle type field to indicate the device type. According to ACPI specification, the device handle type value of 1 represents PCI device, not 0.
