As of commit 3527ed81ca01bbaf09df952e68528377a9cd092f
("PCI: remove secondary/subordinate in struct pci_bus") in linux-next, the
"subordinate" field no longer exists:

http://kisskb.ellerman.id.au/kisskb/buildresult/6546355/
arch/tile/kernel/pci_gx.c:852:31: error: 'struct pci_bus' has no
member named 'subordinate'
make[3]: *** [arch/tile/kernel/pci_gx.o] Error 1

when I'm talking to journalists I just say "programmer" or something like that.
