Routine Description:

    Restore processor specific features.  This routine is called
    when processors have been restored to a powered on state to
    restore those things which are not part of the processor's
    "normal" context which may have been lost.  For example, this
    routine is called when a system is resumed from hibernate or
    suspend.

Arguments:

    None.

Return Value:

    None.

Routine Description:

    Saves all processor-specific state that must be preserved
    across an S4 state (hibernation).

Arguments:

    ProcessorState - Supplies the KPROCESSOR_STATE where the
        current CPU's state is to be saved.

Return Value:

    None.

/*++

Routine Description:

    This function exists solely to instantiate functions that are:

    - Exported from the kernel
    - Inlined within the kernel
    - For whatever reason are not instantiated elsewhere in the kernel
