Subject: [PATCH 06/15] PCI/acpiphp: Convert "acpiphp" sub-driver's functionality to built-in only
Date: Thu, 06 Dec 2012 23:25:30 -0700	[thread overview]
Message-ID: <20121207062530.11051.47869.stgit@amt.stowe> (raw)
In-Reply-To: <20121207062454.11051.12739.stgit@amt.stowe>

The "ACPI Hot Plug PCI Controller ("acpiphp")" 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 "acpiphp" 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.
