change how much of the param string is copied into the kenel

Set locked flag if required
make SC always return success -- this needs to be fixed at some point
fix a couple of things

FS executes a bit of console code before dying a horrible death

arch/alpha/linux/system.cc:
    only need to copy the length of the os flags param, not 256  bytes
cpu/simple/cpu.cc:
    Set the physical flag if required
    Make LL/SC always return success
mem/bus.cc:
    add some dprintfs and change a assert to a panic
mem/port.cc:
    delete the buffer with the [] operator
mem/request.hh:
    add a function to reset a request
