235 Note: The SMP8759 controller multiplexes PCI config and MMIO
236 accesses, and Linux doesn't provide a way to serialize them.
237 This can lead to data corruption if drivers perform concurrent
238 config and MMIO accesses.

245 Adds support for the Intel Volume Management Device (VMD). VMD is a
246 secondary PCI host bridge that allows PCI Express root ports,
247 and devices attached to them, to be removed from the default
248 PCI domain and placed within the VMD domain. This provides
249 more bus resources than are otherwise possible with a
250 single domain. If you know your system provides one of these and
251 has devices attached to it, say Y; if you are not sure, say N.
