Hi,
[I guess this is an RTAI problem, so I put the RTAI ML in cc]

I don't have a powerpc, but when grepping through the source of
rtai-3.0r3, I get

[klaas_at_c014 /usr/src/rtai-3.0r3]$
$ grep -r rt_request_global_irq_arg *
rtai-core/include/asm-ppc/rtai.h:extern int rt_request_global_irq_arg(unsigned int irq,
rtai-doc/generated/html/asm-ppc_2rtai_8h-source.html:00156 <span class="keyword">extern</span> <span class="keywordtype">int</span>  rt_request_global_irq_arg(<span class="keywordtype">unsigned</span> <span class="keywordtype">int</span> irq,

So this function only seems to be declared (and not implemented) in the
powerpc tree.

While searching the ML, I also found this thread with the unanswered
question...
