Hi there

The recent consolidation of the IRQ code has caused
a number of PPC embedded cpus to stop working.

The problem is that on init_IRQ these platforms call
request_irq very early, which in turn calls kmalloc
without the memory subsystem being initialized.

The following patch fixes it by keeping a small static
array of irqactions just for this purpose.



this is quite broken. Those places should use setup_irq(),
not request_irq().

Sorry, didn't know about setup_irq.

Will fix.
