 Module Name:   src
 Committed By:  ozaki-r

 Modified Files:
        src/sys/dev/pci: if_vioif.c
 
 Log Message:
 Don't set SOFTINT_MPSAFE to vioif_rx_softint
 
 vioif_rx_softint calls vioif_populate_rx_mbufs that is not MPSAFE.
 vioif_populate_rx_mbufs is also called via vioif_ioctl and so can
 be called by two LWPs simultaneously, resulting in kernel panic.
