    Subject[BKPATCH] boot hang in migration threads with 2.5.9 and 2.5.10
    Date
    From
    This is an obvious and simple one line fix for a missing CPU logical to 
    physical mapping (against 2.5.9). Without this, my SMP boxes hang forever
    after printing out the migration thread start information.
