+Subject: ACPICA: AML interpreter: add region addresses in global list during initialization
+
+From: Erik Schmauss <erik.schmauss@intel.com>
+
+commit 4abb951b73ff0a8a979113ef185651aa3c8da19b upstream.
+
+The table load process omitted adding the operation region address
+range to the global list. This omission is problematic because the OS
+queries the global list to check for address range conflicts before
+deciding which drivers to load. This commit may result in warning
+messages that look like the following:
+
+[    7.871761] ACPI Warning: system_IO range 0x00000428-0x0000042F conflicts with op_region 0x00000400-0x0000047F (\PMIO) (20180531/utaddress-213)
+[    7.871769] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
+
+However, these messages do not signify regressions. It is a result of
+properly adding address ranges within the global address list.
