[POWERPC] Fix xics set_affinity code
On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error:
xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20
In a desperate attempt to get a changelog entry in 2.6.23, I took a look
into it.
It turns out we are passing a real and not a virtual irq into
get_irq_server. This works for the case where hwirq < NR_IRQS and we
set virq = hwirq. In my case however hwirq = 590082 and we try and
access irq_desc[590082], slightly past the end at 512 entries.
Lucky we ship lots of memory with our machines.
