Routine Description:

    Initialize hal pcr values for current processor (if any)
    (called shortly after processor reaches kernel, before
    HalInitSystem if P0)

    IPI's and KeReadir/LowerIrq's must be available once this function
    returns.  (IPI's are only used once two or more processors are
    available)

Arguments:

    Number - Logical processor number of calling processor

Return Value:

    None.
