[PATCH] PA-RISC GSC interrupt fixes
Two problems occurred with the recent switch to virtual interrupt numbers.
The first is that two devices (eg Lasi PS/2 mouse and keyboard) can
share the same physical interrupt and should therefore share the same
virtual interrupt rather than have a new one assigned to them. Fix this
by initialising the global_irq array to NO_IRQ, then checking the array
before assigning a new one.
The second is that some GSC devices (eg HIL and EISA) can have
two interrupts; one for normal interrupts and the other for NMI or
high-priority. To fix this, I introduced an auxiliary IRQ to the
parisc_device and fill it in in Asp and Wax.
