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.
