Myron Stowe - Dec. 7, 2012, 6:26 a.m.
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.
