This series adds a pci_swizzle_interrupt_pin() function in the PCI
core. Most architectures currently implement this independently.
After this series, many of the callers of pci_swizzle_interrupt_pin()
follow a similar pattern. I'd like to consolidate those callers, too,
but I haven't started that yet.
One strange thing I'd like to understand eventually is why the
swizzle in acpi_pci_irq_derive() does something special for CardBus
bridges, while no other architecture does.
Comments welcome.
These patches have been compile-tested on:
alpha
arm
ia64
mips
powerpc (ppc64)
sh
x86 (32-bit)
x86 (64-bit)
I've boot-tested these architectures:
ia64
x86 (32-bit)
I haven't compiled parisc for want of a cross-compiler.
