 Modified Files:
 	src/sys/dev/pci: virtio_pci.c
 
 Log Message:
 virtio@pci: Nix useless sc_mapped_iosize.
 
 This appears to have been a mistaken attempt to pass the subregion
 length through to bus_space_unmap, which doesn't make any sense --
 bus_space_subregion does not allocate anything and the resulting
 handle must not be passed to bus_space_unmap.
 
 Once we pass the size that was actually returned by pci_mapreg_map to
 bus_space_unmap, which matches the size passed internally by
 pci_mapreg_map to bus_space_map, sc_mapped_iosize is no longer used
 and can be flushed.
 
 Prompted by PR kern/58335.
