+Subject: [PATCH 1/4] PCI/ACPI: Evaluate PCI Boot Configuration _DSM
+Origin: https://git.kernel.org/linus/a78cf9657ba5426f54aa93a067c10d097944c082
+
+Evaluate _DSM Function #5, the "PCI Boot Configuration" function.  If the
+result is 0, the OS should preserve any resource assignments made by the
+firmware.
