From: Sven Joachim svenjoac@gmx.de

commit a9e6d44ddeccd3522670e641f1ed9b068e746ff7 upstream.

After upgrading an old laptop to 4.15-rc9, I found that the eth0 and wlan0 interfaces had disappeared. It turns out that the b43 and b44 drivers require SSB_PCIHOST_POSSIBLE which depends on PCI_DRIVERS_LEGACY, a config option that only exists on Mips.
