From ef09c4f578147464524041cbe3205bb25f900598 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Mon, 14 Feb 2011 16:13:25 +0800 Subject: ACPICA: Add mechanism to defer _REG methods for some installed handlers The memory/io/pci/dataTable regions must always be available. For any user installed handlers for these spaces, defer execution of _REG methods until acpi_enable_subsystem. This prevents any chicken/egg problems and ensures that no methods are executed until all of these regions are ready and available.
