    Subject[PATCH] sched: Enable arch-specific asym packing option in sched domain
    Add arch specific (weak) routine to set (or not set) the ASYM_PACKING
    sched domain flag. This change itself does nothing, but allows archs
    that require asym-packing option to set it by implementing the arch
    specific routine to turn it on.

    The weak symbol is already defined in sched_fair.c but was mis-spelled
    in the header file. Fixed spelling error in the weak symbol definition.
