This seems unrelated to the other macros, since is shifts left only 3 positions. Can you perhaps move it to the end and add a comment as to what the input is and what it returns? It seems different to the others.
#define PCI_DEVFN(d, f) ((d) << 11 | (f) << 8) #define PCI_MASK_BUS(bdf) ((bdf) & 0xffff)
#define PCI_ADD_BUS(bus, devfn) (((bus) << 16) | (devfn))
