Author: bz Date: Fri May 13 11:18:27 2016 New Revision: 299658 URL: https://svnweb.freebsd.org/changeset/base/299658
Log: When using IOPORT with pci_host_generic we are missing setting the rman_end() which leads to end being before start and thus a signed extended very large number of size later on, which kva_alloc() will fail upon and we will panic. Add the missing call.
