Hi Bharat,
Why do you say pci_fixup_irqs is ARM-specific? It's declared in
include/linux/pci.h, defined in drivers/pci/setup-irq.c & used by
multiple architectures (alpha, arm, m68k, mips, sh, sparc, tile,
unicore32 from a quick grep).
Will you not break INTX-style interrupts by removing this?
Thanks,
Paul
