Author: royger Date: Fri Aug 22 15:05:51 2014 New Revision: 270332 URL: http://svnweb.freebsd.org/changeset/base/270332 Log: pci: add a new pci_child_added newbus method. This is needed so when running under Xen the calls to pci_child_added can be intercepted and a custom Xen method can be used to register those devices with Xen. This should not include any functional change, since the Xen implementation will be added in a following patch and the native implementation is a noop.
