    [SPARC64]: Fix more of_device layer IRQ bugs, and correct PROMREG_MAX. · 46ba6d7d
    David S. Miller authored
    Sabre and Psycho PCI controllers can have partial interrupt-map
    properties, meaning that on-board devices don't match up to any
    entries.  Instead, they are fully specified from the beginning and
    we should pass them directly to the IRQ translator as-is.
    
    Also, fill in the necessary translator slots for the "graphics"
    and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS.
    
    Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices.
    
    Finally, prevent accidentally writing past the end of the of_device
    struct resource[] and irqs[] arrays.  Spit out a log message when
    we ignore some entries because there are too many of them.
