merge from head of m5.  note:  i did not bother to merge the PIO stuff with scsi since we're not going that route anymore anyway.  esp because it was giving me an error i couldn't seem to fix.

dev/alpha_console.cc:
    missed this >>>> after i merged
kern/linux/linux_system.cc:
    get rid of FS_MEASURES and change FnEvent to LinuxFnEvent
kern/linux/linux_system.hh:
    get rid of FS_MEASURE
