From mboxrd@z Thu Jan 1 00:00:00 1970 From: Myron Stowe Subject: [PATCH 13/15] PCI/ACPI: Convert "pci_slot" sub-driver's functionality to built-in only Date: Thu, 06 Dec 2012 23:26:11 -0700 Message-ID: <20121207062611.11051.39999.stgit@amt.stowe> References: <20121207062454.11051.12739.stgit@amt.stowe> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from mx1.redhat.com ([209.132.183.28]:52334 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1946003Ab2LGG0O (ORCPT ); Fri, 7 Dec 2012 01:26:14 -0500 In-Reply-To: <20121207062454.11051.12739.stgit@amt.stowe> Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: bhelgaas@google.com Cc: linux-pci@vger.kernel.org, yinghai@kernel.org, linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org The "ACPI PCI Slot Detection ("pci_slot")" sub-driver may be compiled as a module. Kernel modules are instantiated somewhat randomly - the order in which they are linked as the kernel as built - thus if there are any dependencies on the ordering of attaching sub-drivers, they can not be effectively dealt with. This patch series resolves any potential sequencing inter-dependencies by converting "pci_slot" sub-driver's functionality to being only supported as statically built-in to the kernel. Inter-dependencies can then be effectively handled by explicitly sequencing the addition of such functionality.
