This breaks at least arm64 (as you can see from the reply to patch #5,
because it does have its own asm/pci.h. Instead, how about moving this
to linux/pci.h, just after the include of asm/pci.h? I just gave it a
go, and it seems to work nicely (the first hunk fixes the rest of the
arm64 compile issue):
