From b95a7bd700466c10fda84acbd33f70cf66ec91ce Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 6 Dec 2011 07:49:30 +0000 Subject: pci, x86/io-apic: Allow PCI_IOAPIC to be user configurable on x86 This adjusts PCI_IOAPIC to be user configurable (possibly as a module) on x86, since the base architecture code for adding IO-APICs dynamically isn't there yet (and hence having the code present everywhere is pretty pointless). To make this consistent, a MODULE_DEVICE_TABLE() declaration gets added, the class specifications get corrected (by properly using PCI_DEVICE_CLASS() intended for purposes like this), and the probe and remove functions get their sections adjusted.
