From: "Rafael J. Wysocki" <[email protected]> There is no reason (knwon to me) why any of the existing users of acpi_os_unmap_generic_address() would need to wait for the unused memory mappings left by it to actually go away, so use the deferred unmapping of ACPI memory introduced previously in that function.
