Behavior can still be controlled using the pci=realloc= parameter. -v2: According to Jesse, adding one CONFIG option for distribution to disable it or enable it. -v3: update Kconfig text (jbarnes) Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> 2011-12-06T08:21:05+00:00 Jan Beulich JBeulich@suse.com 2011-12-06T07:49:30+00:00 urn:sha1:b95a7bd700466c10fda84acbd33f70cf66ec91ce 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.
