We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.

I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

This comment seems to suggest PCI_GENERIC_SETUP should be added a few
lines up to preserve the alphabetical sorting.

Whoops -- I guess I was just on autopilot after seeing the first one not be
alphabetized.  A fixed patch is in a threaded message.

Looks fine from an ARM point of view, thanks.

	bool

would be sufficient here - the default is 'n' for all options.

Lorenzo Pieralisi's "ARM/ARM64: remove pci_fixup_irqs() usage" series
overlaps with this quite a bit, and includes this patch:

https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/commit/?h=pci/enumeration&id=5b64036feff4

which makes it so we build setup-irq.o on *all* arches.  Can you check
out the pci/enumeration branch and see whether it accomplishes what
you need?

https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/enumeration

Great, that's even better for me, as I don't have to go touch a bunch of
different arch code :).  We'll use that instead when it lands.
