    [SPARC]: Kill __irq_itoa(). · c6387a48

    This ugly hack was long overdue to die.
    It was a way to print out Sparc interrupts in a more freindly format,
    since IRQ numbers were arbitrary opaque 32-bit integers which vectored
    into PIL levels.  These 32-bit integers were not necessarily in the
    0-->NR_IRQS range, but the PILs they vectored to were.
    The idea now is that we will increase NR_IRQS a little bit and use a
    virtual<-->real IRQ number mapping scheme similar to PowerPC.
    That makes this IRQ printing hack irrelevant, and furthermore only a
    handful of drivers actually used __irq_itoa() making it even less
