From 3fb02738b0fd36f47710a2bf207129efd2f5daa2 Mon Sep 17 00:00:00 2001 From: Rajesh Shah Date: Thu, 28 Apr 2005 00:25:52 -0700 Subject: [PATCH] acpi bridge hotadd: Allow ACPI .add and .start operations to be done independently Create new interfaces to recursively add an acpi namespace object to the acpi device list, and recursively start the namespace object. This is needed for ACPI based hotplug of a root bridge hierarchy where the add operation must be performed first and the start operation must be performed separately after the hot-plugged devices have been properly configured.
